* Add `RackAwareAssignor`. It uses `racksForPartition` to check the rack
id of a partition and assign it to a member which has the same rack id.
* Add `ConsumerIntegrationTest#testRackAwareAssignment` to check
`racksForPartition` works correctly.

Adding support for the `urn:ietf:params:oauth:grant-type:jwt-bearer`
grant type (AKA `jwt-bearer`). Includes further refactoring of the
existing OAuth layer and addition of generic JWT assertion layer that
can be leveraged in the future.
This constitutes the main piece of the JWT Bearer grant type support.
Forthcoming commits/PRs will include improvements for both the
`client_credentials` and `jwt-bearer` grant types in the following
areas:
* Integration test coverage (KAFKA-19153)
* Unit test coverage (KAFKA-19308)
* Top-level documentation (KAFKA-19152)
* Improvements to and documentation for `OAuthCompatibilityTool`

The main issue was that we forgot to set
`TopicConfig.SEGMENT_BYTES_CONFIG` to at least `1024 * 1024`, which
caused problems in tests with small segment sizes.
To address this, we introduced a new internal config:
`LogConfig.INTERNAL_SEGMENT_BYTES_CONFIG`, allowing us to set smaller
segment bytes specifically for testing purposes.
We also updated the logic so that if a user configures the topic-level
segment bytes without explicitly setting the internal config, the
internal value will no longer be returned to the user.
In addition, we removed
`MetadataLogConfig#METADATA_LOG_SEGMENT_MIN_BYTES_CONFIG` and added
three new internal configurations:
- `INTERNAL_MAX_BATCH_SIZE_IN_BYTES_CONFIG`
- `INTERNAL_MAX_FETCH_SIZE_IN_BYTES_CONFIG`
- `INTERNAL_DELETE_DELAY_MILLIS_CONFIG`

Separates metadata-related configurations from the `KRaftConfigs` into
the `MetadataLogConfig` class.
Previously, metadata-related configs were placed in `KRaftConfigs`,
which mixed server-related configs (like process.roles) with
metadata-specific ones (like metadata.log.*), leading to confusion and
tight coupling.
In this PR:
- Extract metadata-related config definitions and variables from
`KRaftConfig` into `MetadataLogConfig`.
- Move `node.id` out of `MetadataLogConfig` into `KafkaMetadataLog’s
constructor` to avoid redundant config references.
- Leave server-related configurations in `KRaftConfig`, consistent with
its role.
This separation makes `KafkaConfig` and `KRaftConfig` cleaner, and
aligns with the goal of having a dedicated MetadataLogConfig class for
managing metadata-specific configurations.

If Log4j Core is absent, most calls to Log4jController and Loggers will end up with a NoClassDefFoundError.
This changeset:
- Profits from the major version bump to rename k.util.Log4jController to LoggingController.
- Removes o.a.l.l.Level from the signature of public methods of o.a.k.connect.runtime.Loggers and replaces it with String.
- Provides an additional no-op implementation of k.util.LoggingController and o.a.k.connect.runtime.Loggers: if Log4j Core is not present on the runtime classpath the no-op implementation will be used.

This patch reorganizes our test infrastructure into three Gradle modules:
":test-common:test-common-internal-api" is now a minimal dependency which exposes interfaces and annotations only. It has one project dependency on server-common to expose commonly used data classes (MetadataVersion, Feature, etc). Since this pulls in server-common, this module is Java 17+. It cannot be used by ":clients" or other Java 11 modules.
":test-common:test-common-util" includes the auto-quarantined JUnit extension. The @Flaky annotation has been moved here. Since this module has no project dependencies, we can add it to the Java 11 list so that ":clients" and others can utilize the @Flaky annotation
":test-common:test-common-runtime" now includes all of the test infrastructure code (TestKitNodes, etc). This module carries heavy dependencies (core, etc) and so it should not normally be included as a compile-time dependency.
In addition to this reorganization, this patch leverages JUnit SPI service discovery so that modules can utilize the integration test framework without depending on ":core". This will allow us to start moving integration tests out of core and into the appropriate sub-module. This is done by adding ":test-common:test-common-runtime" as a testRuntimeOnly dependency rather than as a testImplementation dependency. A trivial example was added to QuorumControllerTest to illustrate this.

Remove Apache ZooKeeper from the Apache Kafka build. Also remove commons IO, commons CLI, and netty, which were dependencies we took only because of ZooKeeper.
In order to keep the size of this PR manageable, I did not remove all classes which formerly interfaced with ZK. I just removed the ZK types. Fortunately, Kafka generally wrapped ZK data structures rather than using them directly.
Some classes were pretty entangled with ZK, so it was easier just to stub them out. For ZkNodeChangeNotificationListener.scala, PartitionStateMachine.scala, ReplicaStateMachine.scala, KafkaZkClient.scala, and ZookeeperClient.scala, I replaced all the functions with "throw new UnsupportedOperationException". Since the tests for these classes have been removed, as well as the ZK-based broker code, this should be OK as an incremental step.

This commit implements the changes for KIP-1032. This updates Kafka to Jakarta specs, JavaEE 10 and Jetty 12. The changes here primarily effect Kafka Connect and MM2.
Todo/Notes:
1) I bumped the connect modules to JDK 17 but I also had to bump a couple other things that had a dependency on conect. The tools project depends on connect so that had to be bumped, and streams depends on tools so that needed to be bumped. This means we may need to separate some things if we don't want to enforce JDK 17 on streams.
2) There is an issue with a test in DedicatedMirrorIntegrationTest that I had to change for now that involves escaping characters and not quite sure what to do about it yet. The cause is the Servlet 6 spec changing what is allowed in the path. See: Jetty 12: 400: Ambiguous URI path encoding for path <%=FOO%>~1 (encoded: %3C%25%3DFOO%25%3E%7E1) jetty/jetty.project#11890
3) I had to configure the idle timeout in Jetty requests to match our request timeout so tests didn't fail. This was needed to fix the ConnectWorkerIntegrationTest#testPollTimeoutExpiry() test
Testing is being done by just using the existing tests for Connect and MM2 which should be sufficient.

This PR adds support for add-controller and remove-controller in the kafka-metadata-quorum.sh
command-line tool. It also fixes some minor server-side bugs that blocked the tool from working.
In kafka-metadata-quorum.sh, the implementation of remove-controller is fairly straightforward. It
just takes some command-line flags and uses them to invoke AdminClient. The add-controller
implementation is a bit more complex because we have to look at the new controller's configuration
file. The parsing logic for the advertised.listeners and listeners server configurations that we
need was previously implemented in the :core module. However, the gradle module where
kafka-metadata-quorum.sh lives, :tools, cannot depend on :core. Therefore, I moved listener parsing
into SocketServerConfigs.listenerListToEndPoints. This will be a small step forward in our efforts
to move Kafka configuration out of :core.
I also made some minor changes in kafka-metadata-quorum.sh and Kafka-storage-tool.sh to handle
--help without displaying a backtrace on the screen, and give slightly better error messages on
stderr. Also, in DynamicVoter.toString, we now enclose the host in brackets if it contains a colon
(as IPV6 addresses can).
This PR fixes our handling of clusterId in addRaftVoter and removeRaftVoter, in two ways. Firstly,
it marks clusterId as nullable in the AddRaftVoterRequest.json and RemoveRaftVoterRequest.json
schemas, as it was always intended to be. Secondly, it allows AdminClient to optionally send
clusterId, by using AddRaftVoterOptions and RemoveRaftVoterOptions. We now also remember to
properly set timeoutMs in AddRaftVoterRequest. This PR adds unit tests for
KafkaAdminClient#addRaftVoter and KafkaAdminClient#removeRaftVoter, to make sure they are sending
the right things.
Finally, I fixed some minor server-side bugs that were blocking the handling of these RPCs.
Firstly, ApiKeys.ADD_RAFT_VOTER and ApiKeys.REMOVE_RAFT_VOTER are now marked as forwardable so that
forwarding from the broker to the active controller works correctly. Secondly,
org.apache.kafka.raft.KafkaNetworkChannel has now been updated to enable API_VERSIONS_REQUEST and
API_VERSIONS_RESPONSE.

Allow KRaft replicas to send requests to any node (Node) not just the nodes configured in the
controller.quorum.voters property. This flexibility is needed so KRaft can implement the
controller.quorum.voters configuration, send request to the dynamically changing set of voters and
send request to the leader endpoint (Node) discovered through the KRaft RPCs (specially
BeginQuorumEpoch request and Fetch response).
This was achieved by changing the RequestManager API to accept Node instead of just the replica ID.
Internally, the request manager tracks connection state using the Node.idString method to match the
connection management used by NetworkClient.
The API for RequestManager is also changed so that the ConnectState class is not exposed in the
API. This allows the request manager to reclaim heap memory for any connection that is ready.
The NetworkChannel was updated to receive the endpoint information (Node) through the outbound raft
request (RaftRequent.Outbound). This makes the network channel more flexible as it doesn't need to
be configured with the list of all possible endpoints. RaftRequest.Outbound and
RaftResponse.Inbound were updated to include the remote node instead of just the remote id.
The follower state tracked by KRaft replicas was updated to include both the leader id and the
leader's endpoint (Node). In this comment the node value is computed from the set of voters. In
future commit this will be updated so that it is sent through KRaft RPCs. For example
BeginQuorumEpoch request and Fetch response.
Support for configuring controller.quorum.bootstrap.servers was added. This includes changes to
KafkaConfig, QuorumConfig, etc. All of the tests using QuorumTestHarness were changed to use the
controller.quorum.bootstrap.servers instead of the controller.quorum.voters for the broker
configuration. Finally, the node id for the bootstrap server will be decreasing negative numbers
starting with -2.
