https://github.com/apache/kafka/pull/12951 accidentally changed the behavior of the `kafaka-metadata-quorum.sh` CLI by making it silently ignore a `--command-config <filename>` properties file that exists. This was an undetected regression in the 3.4.0 release. This patch fixes the issue such that any such specified file will be honored.

In MetadataQuorumCommandTest, we sometimes got the error:
java.util.concurrent.ExecutionException: java.lang.RuntimeException: Received a fatal error while waiting for the broker to catch up with the current cluster metadata.
Since we tried to bring up 3 broker + 3 controllers at the same time, and the config initial.broker.registration.timeout.ms (default 1 min) is sometimes not enough for them to start up. Checking the tests, it doesn't require so many nodes. Reducing the nodes number to make these tests reliable.

`core` should only be used for legacy cli tools and tools that require
access to `core` classes instead of communicating via the kafka protocol
(typically by using the client classes).
Summary of changes:
1. Convert the command implementation and tests to Java and move it to
the `tools` module.
2. Introduce mechanism to capture stdout and stderr from tests.
3. Change `kafka-metadata-quorum.sh` to point to the new command class.
4. Adjusted the test classpath of the `tools` module so that it supports tests
that rely on the `@ClusterTests` annotation.
5. Improved error handling when an exception different from `TerseFailure` is
thrown.
6. Changed `ToolsUtils` to avoid usage of arrays in favor of `List`.

* KAFKA-13725: KIP-768 OAuth code mixes public and internal classes in same package
Move classes into a sub-package of "internal" named "secured" that
matches the layout more closely of the "unsecured" package.
Replaces the concrete implementations in the former packages with
sub-classes of the new package layout and marks them as deprecated. If
anyone is already using the newer OAuth code, this should still work.

This patch fixes some strangeness and inconsistency in the messages written by `TransactionalMessageCopier` to stdout. Here is a sample of two messages.
Progress message:
```
{"consumed":33000,"stage":"ProcessLoop","totalProcessed":33000,"progress":"copier-0","time":"2022/04/24 05:40:31:649","remaining":333}
```
The `transactionalId` is set to the value of the `progress` key.
And a shutdown message:
```
{"consumed":33333,"shutdown_complete":"copier-0","totalProcessed":33333,"time":"2022/04/24 05:40:31:937","remaining":0}
```
The `transactionalId` this time is set to the `shutdown_complete` key and there is no `stage` key.
In this patch, we change the following:
1. Use a separate key for the `transactionalId`.
2. Drop the `progress` and `shutdown_complete` keys.
3. Use `stage=ShutdownComplete` in the shutdown message.
4. Modify `transactional_message_copier.py` system test service accordingly.

The class PushHttpMetricsReporter no longer pushes metrics when network failure is recovered.
I debugged the code and found the problem here: when we submit a task to the ScheduledThreadPoolExecutor that needs to be executed periodically, if the task throws an exception and is not swallowed, the task will no longer be scheduled to execute.
So when an IO exception occasionally occurs on the network, we should swallow it rather than throw it in task HttpReporter.

This task is to provide a concrete implementation of the interfaces defined in KIP-255 to allow Kafka to connect to an OAuth/OIDC identity provider for authentication and token retrieval. While KIP-255 provides an unsecured JWT example for development, this will fill in the gap and provide a production-grade implementation.
The OAuth/OIDC work will allow out-of-the-box configuration by any Apache Kafka users to connect to an external identity provider service (e.g. Okta, Auth0, Azure, etc.). The code will implement the standard OAuth client credentials grant type.
The proposed change is largely composed of a pair of AuthenticateCallbackHandler implementations: one to login on the client and one to validate on the broker.

This patch has a couple small improvements to `TransactionalMessageCopier` logging:
- Log all fatal exceptions which cause the copier to shutdown unexpectedly
- Log all non-fatal exceptions which cause the copier to abort a transaction
Reviewers: David Jacot <djacot@confluent.io>
The `TransactionalMessageCopier` tool, which is used in system tests attempts to close the consumer as part of a shutdown hook. Although the access is synchronized, there is no guarantee that the consumer has finished polling when shutdown is invoked. The patch fixes the problem by call `wakeup()` from the shutdown hook and pushing the call to `close()` to the main thread.

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

Reviewers: Colin P. McCabe <cmccabe@apache.org>
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.

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
