The presence of the buildSrc subproject is causing problems when we try
to run installAll, jarAll, and the other "all" targets. It's easier
just to make the generator code a regular subproject and use the
JavaExec gradle task to run the code. This also makes it more
straightforward to run the generator unit tests.

* Join ssl principal mapping rules correctly before evaluating.
Java properties splits the configuration array on commas, and that leads to rules containing commas being split before being evaluated. This commit adds a code change to re-join those strings into full rules before evaluating them. The function assumes every rule is either DEFAULT or begins with the prefix RULE:
The Javadoc is using Properties.put which should never be used because it allows putting non-strings into a Properties object which is designed to only handle strings.
Two other minor fixes so the examples actually work
Let findSessions(final K key) to call on underlying bytes store directly, using the more restricted range.
Fix the conservative upper range for multi-key range in session schema.
Minor: removed unnecessary private WrappedSessionStoreBytesIterator class as it is only used in unit test.
Minor: removed unnecessary schema#init function by using the direct bytes-to-binary function.
Please read the original PR for more detailed explanation of the root cause of the bug.

In RocksDBStore.openDB we call

We would also add the absolute file path as well to avoid the extra logging.

I've observed several reports of sudden unexpected streamthread shutdown with the log entry like:
State transition from PENDING_SHUTDOWN to DEAD
but there is no related error logs before this line at all. I suspect this is because we intentionally do not log for KafkaException and there's some edge cases where we miss internally and hence caused this. I'm adding the ERROR level log entry here in order to reveal more information in case I saw this again in the future.

Update the Trogdor StringExpander regex to handle an epilogue. Previously the regex would use a lazy quantifier at the end, which meant it would not catch anything after the range expression. Add a unit test.

Added testing of logical types for Kafka Connect in support of KIP-145 features.
Added tests for Boolean, Time, Date and Timestamp, including the valid conversions.
The area of ISO8601 strings is a bit of a mess because the tokenizer is not compatible with
that format, and a subsequent JIRA will be needed to fix that.
A few small fixes as well as creating test cases, but they're clearly just corrections such as
using 0 to mean January (java.util.Calendar uses zero-based month numbers).

Expose a programmatic way to bring up a Kafka and Zk cluster through Java API to facilitate integration tests for framework level changes in Kafka Connect. The Kafka classes would be similar to KafkaEmbedded in streams. The new classes would reuse the kafka.server.KafkaServer classes from :core, and provide a simple interface to bring up brokers in integration tests.

Closes#6082 from kamalcph/KAFKA-7781
This patch adds a framework to automatically generate the request/response classes for Kafka's protocol. The code will be updated to use the generated classes in follow-up patches. Below is a brief summary of the included components:
**buildSrc/src**
The message generator code is here. This code is automatically re-run by gradle when one of the schema files changes. The entire directory is processed at once to minimize the number of times we have to start a new JVM. We use Jackson to translate the JSON files into Java objects.
**clients/src/main/java/org/apache/kafka/common/protocol/Message.java**
This is the interface implemented by all automatically generated messages.
**clients/src/main/java/org/apache/kafka/common/protocol/MessageUtil.java**
Some utility functions used by the generated message code.
**clients/src/main/java/org/apache/kafka/common/protocol/Readable.java, Writable.java, ByteBufferAccessor.java**
The generated message code uses these classes for writing to a buffer.
**clients/src/main/message/README.md**
This README file explains how the JSON schemas work.
**clients/src/main/message/\*.json**
The JSON files in this directory implement every supported version of every Kafka API. The unit tests automatically validate that the generated schemas match the hand-written schemas in our code. Additionally, there are some things like request and response headers that have schemas here.
**clients/src/main/java/org/apache/kafka/common/utils/ImplicitLinkedHashSet.java**
I added an optimization here for empty sets. This is useful here because I want all messages to start with empty sets by default prior to being loaded with data. This is similar to the "empty list" optimizations in the `java.util.ArrayList` class.

When I originally refactored the streams_upgrade_test#upgrade_downgrade_brokers test I removed the wait call which would wait for up 24 minutes for the SmokeTestDriver class to publish and verify all of its records.
Since most of the tests run in two minutes or less I set the monitor_log timeout to three minutes. However, the SmokeTestDriver#verify method allows up to six minutes to consume all records before verifying the monitor_log timeout needs to be greater than 6 minutes. I've set the timeout to 8 minutes.
Additionally, the steps needed to update the streams_upgrade_test should be documented as there are several components that need to get updated. So I've documented those steps here on the test as a giant comment.

* KAFKA-6627: Prevent config default values overriding ones specified through --producer-property on command line.
In Console{Producer,Consumer}, extraProducerProps (options specified in
--producer-property) is applied first, then overriden unconditionally,
even if the value is not specified explicitly (and default value is
used). This patch fixes it so that it doesn't override the existing
value set by --producer-property if it is not explicitly specified.

As documented in https://issues.apache.org/jira/browse/KAFKA-7741,
the javax dependency we receive transitively from connect is incompatible
with SBT builds.
Streams doesn't use the portion of Connect that needs the dependency,
so we can fix the builds by simply excluding it.

We recently improved the handling of the InternalTopicManager retries with #6085. The AdminClient will throw an InvalidTopicException if the topic is not found. We need to ignore that exception as when calling AdminClient#describe we may not have had a chance to create the topic yet, especially with the case of internal topics
I've created a new test asserting that when an InvalidTopicException is thrown when the topic is not found we continue on.

There is a race condition in ReplicaFetcherThread, where we can update PartitionFetchState with the new leader epoch (same leader) before handling the OffsetsForLeaderEpoch response with FENCED_LEADER_EPOCH error which causes removing partition from partitionStates, which in turn causes no fetching until the next LeaderAndIsr.
This patch adds logic to ensure that the leader epoch doesn't change while an OffsetsForLeaderEpoch request is in flight (which could happen with back-to-back leader elections). If it has changed, we ignore the response.
Also added toString() implementation to PartitionData, because some log messages did not show useful info which I found while investigating the above system test failure.
