Move Trogdor out of tools and into its own gradle module. This allows us to minimize

The config has been deprecated since Kafka 2.6 (released ~1 year before
3.0), but it was the default before it got deprecated. As such, it's
reasonably unlikely that people would have set it explicitly.
Given the confusing `default` name even though it's _not_ the default, I
think we should remove it in 3.0.
Also remove `ClientDnsLookup.DEFAULT` (not public API), which unlocks
a number of code simplications.

The patch adds `quorum.append.linger.ms` behavior to the raft implementation. This gives users a powerful knob to tune the impact of fsync. When an append is accepted from the state machine, it is held in an accumulator (similar to the producer) until the configured linger time is exceeded. This allows the implementation to amortize fsync overhead at the expense of some write latency.
The patch also improves our methodology for testing performance. Up to now, we have relied on the producer performance test, but it is difficult to simulate expected controller loads because producer performance is limited by other factors such as the number of producer clients and head-of-line blocking. Instead, this patch adds a workload generator which runs on the leader after election.
Finally, this patch brings us nearer to the write semantics expected by the KIP-500 controller. It makes the following changes:
- Introduce `RecordSerde<T>` interface which abstracts the underlying log implementation from `RaftClient`. The generic type is carried over to `RaftClient<T>` and is exposed through the read/write APIs.
- `RaftClient.append` is changed to `RaftClient.scheduleAppend` and returns the last offset of the expected log append.
- `RaftClient.scheduleAppend` accepts a list of records and ensures that the full set are included in a single batch.
- Introduce `RaftClient.Listener` with a single `handleCommit` API which will eventually replace `RaftClient.read` in order to surface committed data to the controller state machine. Currently `handleCommit` is only used for records appended by the leader.

This change sets the groundwork for migrating other modules incrementally.
Main changes:
- Replace `junit` 4.13 with `junit-jupiter` and `junit-vintage` 5.7.0-RC1.
- All modules except for `tools` depend on `junit-vintage`.
- `tools` depends on `junit-jupiter`.
- Convert `tools` tests to JUnit 5.
- Update `PushHttpMetricsReporterTest` to use `mockito` instead of `powermock` and `easymock`
(powermock doesn't seem to work well with JUnit 5 and we don't need it since mockito can mock
static methods).
- Update `mockito` to 3.5.7.
- Update `TestUtils` to use JUnit 5 assertions since `tools` depends on it.
Unrelated clean-ups:
- Remove `unit` from package names in a few `core` tests.
- Replace `try/catch/fail` with `assertThrows` in a number of places.
- Tag `CoordinatorTest` as integration test.
- Remove unnecessary type parameters when invoking methods and constructors.

Creating a topic may fail (due to timeout) in running system tests. However, `RoundTripWorker` does not ignore `TopicExistsException` which makes `round_trip_fault_test.py` be a flaky one.

This change mainly have 2 components:
1. extend the existing transactions_test.py to also try out new sendTxnOffsets(groupMetadata) API to make sure we are not introducing any regression or compatibility issue
a. We shrink the time window to 10 seconds for the txn timeout scheduler on broker so that we could trigger expiration earlier than later
2. create a completely new system test class called group_mode_transactions_test which is more complicated than the existing system test, as we are taking rebalance into consideration and using multiple partitions instead of one. For further breakdown:
a. The message count was done on partition level, instead of global as we need to visualize
the per partition order throughout the test. For this sake, we extend ConsoleConsumer to print out the data partition as well to help message copier interpret the per partition data.
b. The progress count includes the time for completing the pending txn offset expiration
c. More visibility and feature improvements on TransactionMessageCopier to better work under either standalone or group mode.

The consumer's `committed` API does not return an entry in the response map for a requested partition if there is no committed offset. The transactional message copier, which is used in the transaction system test, did not account for this. If the first transaction attempted by the copier was randomly aborted, then we would not seek to the beginning as expected, which means we would fail to copy some of the records.
This patch fixes the problem by iterating over the assignment rather than the result of `committed` when resetting offsets. It also adds enables additional logging in the transaction message copier service to make finding problems easier in the future.

This creates a test that generates sustained connections against Kafka. There
are three different components we can stress with this, KafkaConsumer,
KafkaProducer, and AdminClient. This test tries use minimal bandwidth per
connection to reduce overhead impacts.
This test works by creating a threadpool that creates connections and then
maintains a central pool of connections at a specified keepalive rate. The
keepalive action varies by which component is being stressed:
* KafkaProducer: Sends one single produce record. The configuration for
the produce request uses the same key/value generator as the ProduceBench
test.
* KafkaConsumer: Subscribes to a single partition, seeks to the end, and
then polls a minimal number of records. Each consumer connection is its
own consumer group, and defaults to 1024 bytes as FETCH_MAX_BYTES to keep
traffic to a minimum.
* AdminClient: Makes an API call to get the nodes in the cluster.
NOTE: This test is designed to be run alongside a ProduceBench test for a
specific topic, due to the way the Consumer test polls a single partition.
There may be no data returned by the consumer test if this is run on its own.
The connection should still be kept alive, but with no data returned.

For static members join/rejoin, we encode the current timestamp in the new member.id. The format looks like group.instance.id-timestamp.
During consumer/broker interaction logic (Join, Sync, Heartbeat, Commit), we shall check the whether group.instance.id is known on group. If yes, we shall match the member.id stored on static membership map with the request member.id. If mismatching, this indicates a conflict consumer has used same group.instance.id, and it will receive a fatal exception to shut down.
Right now the only missing part is the system test. Will work on it offline while getting the major logic changes reviewed.

This is the first diff for the implementation of JoinGroup logic for static membership. The goal of this diff contains:
* Add group.instance.id to be unique identifier for consumer instances, provided by end user;
Modify group coordinator to accept JoinGroupRequest with/without static membership, refactor the logic for readability and code reusability.
* Add client side support for incorporating static membership changes, including new config for group.instance.id, apply stream thread client id by default, and new join group exception handling.
* Increase max session timeout to 30 min for more user flexibility if they are inclined to tolerate partial unavailability than burdening rebalance.
* Unit tests for each module changes, especially on the group coordinator logic. Crossing the possibilities like:
6.1 Dynamic/Static member
6.2 Known/Unknown member id
6.3 Group stable/unstable
6.4 Leader/Follower
The rest of the 345 change will be broken down to 4 separate diffs:
* Avoid kicking out members through rebalance.timeout, only do the kick out through session timeout.
* Changes around LeaveGroup logic, including version bumping, broker logic, client logic, etc.
* Admin client changes to add ability to batch remove static members
* Deprecate group.initial.rebalance.delay

Implement destroying tasks and workers. This means erasing all record of them on the Coordinator and the Agent.
Workers should be identified by unique 64-bit worker IDs, rather than by the names of the tasks they are implementing. This ensures that when a task is destroyed and re-created with the same task ID, the old workers will be not be treated as part of the new task instance.
Fix some return results from RPCs. In some cases RPCs were returning values that were never used. Attempting to re-create the same task ID with different arguments should fail. Add RequestConflictException to represent HTTP error code 409 (CONFLICT) for this scenario.

The behavior of producer bench is changed such that if some or all topics already exist (with topic names = topicPrefix + topic index), and they have the same number of partitions as requested, the worker uses those topics and does not fail. The producer bench fails if one or more existing topics has number of partitions that is different from expected number of partitions.

When a log entry is appended to a Kafka topic using `KafkaLog4jAppender`, the producer.send operation may block waiting for metadata. This can result in deadlocks in a couple of scenarios if a log entry from the producer network thread is also at a log level that results in the entry being appended to a Kafka topic.
1. Producer's network thread will attempt to send data to a Kafka topic and this is unsafe since producer.send may block waiting for metadata, causing a deadlock since the thread will not process the metadata request/response.
2. `KafkaLog4jAppender#append` is invoked while holding the lock of the logger. So the thread waiting for metadata in the initial send will be holding the logger lock. If the producer network thread has.a log entry that needs to be appended, it will attempt to acquire the logger lock and deadlock.
This is a temporary workaround to avoid deadlocks in system tests by setting log level to WARN for `Metadata` in `VerifiableLog4jAppender`. The fix has been verified using the system tests log4j_appender_test.py which started failing when the info-level log entry was introduced.

This is follow up to #4072 which added the PushHttpMetricsReporter and converted some services to use it. We somehow missed some compatibility issues that made the ProducerPerformance tool fail when using a newer tools jar with older common/clients jar, which we do with some system tests so we have all the features we need in the tool but can build compatibility tests for older releases.
This just adjusts some API usage to make the tool compatible with all previous releases.

Previously, Trogdor only handled "Faults." Now, Trogdor can handle
"Tasks" which may be either faults, or workloads to execute in the
background.
The Agent and Coordinator have been refactored from a
mutexes-and-condition-variables paradigm into a message passing
paradigm. No locks are necessary, because only one thread can access
the task state or worker state. This makes them a lot easier to reason
about.
The MockTime class can now handle mocking deferred message passing
(adding a message to an ExecutorService with a delay). I added a
MockTimeTest.
MiniTrogdorCluster now starts up Agent and Coordinator classes in
paralle in order to minimize junit test time.
RPC messages now inherit from a common Message.java class. This class
handles implementing serialization, equals, hashCode, etc.
Remove FaultSet, since it is no longer necessary.
Previously, if CoordinatorClient or AgentClient hit a networking
problem, they would throw an exception. They now retry several times
before giving up. Additionally, the REST RPCs to the Coordinator and
Agent have been changed to be idempotent. If a response is lost, and
the request is resent, no harm will be done.

Multiple inflights means that when there are rolling bounces or other cluster instability, there is an increased likelihood of having previously tried batch expire in the accumulator. This is a fatal error
for a transactional producer, causing the `TransactionalMessageCopier` to exit. To work around this, we bump the request timeout. We can get rid of this when KIP-91 is merged.

Here we introduce client and broker changes to support multiple inflight requests while still guaranteeing idempotence. Two major problems to be solved:
1. Sequence number management on the client when there are request failures. When a batch fails, future inflight batches will also fail with `OutOfOrderSequenceException`. This must be handled on the client with intelligent sequence reassignment. We must also deal with the fatal failure of some batch: the future batches must get different sequence numbers when the come back.
2. On the broker, when we have multiple inflights, we can get duplicates of multiple old batches. With this patch, we retain the record metadata for 5 older batches.

Before this patch, we would call `producerBatch.done` directly from the accumulator when expiring batches. This meant that we would not transition to the `ABORTABLE_ERROR` state in the transaction manager, allowing other transactional requests (including Commits!) to go through, even though the produce failed.
This patch modifies the logic so that we call `Sender.failBatch` on every expired batch, thus ensuring that the transaction state is accurate.

Current implementation of ProducerPerformance creates static payload. This is not very useful in testing compression or when you want to test with production/custom payloads. So, we decided to add support for providing payload file as an input to producer perf test script.
We made the following changes:
1. Added support to provide a payload file which can have the list of payloads that you actually want to send.
2. Moved payload generation inside the send loop for cases when payload file is provided.
Following are the changes to how the producer-performance is evoked:
1. You must provide "--record-size" or "--payload-file" but not both. This is because, record size cannot be guaranteed when you are using custom events.
e.g. ./kafka-producer-perf-test.sh --topic test_topic --num-records 100000 --producer-props bootstrap.servers=127.0.0.1:9092 acks=0 buffer.memory=33554432 compression.type=gzip batch.size=10240 linger.ms=10 --throughput -1 --payload-file ./test_payloads --payload-delimiter ,
2. Earlier "--record-size" was a required config, now you must provide exactly one of "--record-size" or "--payload-file". Providing both will result in an error.
3. Support for an additional parameter "--payload-delimiter" has been added which defaults to "\n"

Added CompressionTest that tests 4 producers, each using a different compression type and one not using compression.
Enabled VerifiableProducer to run producers with different compression types (passed in the constructor). This includes enabling each producer to output unique values, so that the verification process in ProduceConsumeValidateTest is correct (counts acks from all producers).

This needs some refactoring to avoid the duplicated code between replication test and upgrade test, but in shape for initial feedback.
I'm interested in feedback on the added `KafkaConfig` class and `kafka_props` file. This addition makes it:
- easier to attach different configs to different nodes (e.g. during broker upgrade process)
- easier to reason about the configuration of a particular node
Notes:
- in the default values in the KafkaConfig class, I removed many properties which were in kafka.properties before. This is because most of those properties were set to what is already the default value.
- when running non-trunk VerifiableProducer, I append the trunk tools jar to the classpath, and run it with the non-trunk kafka-run-class.sh script
