## Changes
- The partitions == 0 branch has been moved from **waitForTopic** to
**waitTopicDeletion**.
## Reasons
- Clarify the responsibility of each helper method makes the test code
easier to reason by moving the partitions == 0 logic from
**waitForTopic** into a dedicated method **waitTopicDeletion**.

Refactor the code related to SocketServer SocketServer is an internal
class, and normally the integration tests should not use it directly.
[KAFKA-19239](https://issues.apache.org/jira/browse/KAFKA-19239) will
add a new helper to expose the bound ports, and so the tests that need
to send raw request can leverage it without accessing the SocketServer.

This PR rewrites the IntegrationTestUtils.java from Scala to Java.
## Changes:
- Converted all the existing Scala code in IntegrationTestUtils.scala
into Java in IntegrationTestUtils.java.
- Preserved the original logic and functionality to ensure backward
compatibility.
- Updated relevant imports and dependencies accordingly.
Motivation:
The rewrite aims to standardize the codebase in Java, which aligns
better with the rest of the project and facilitates easier maintenance
by the Java-centric team.

In [KIP-1143](https://cwiki.apache.org/confluence/x/LwqWF), it
deprecated Endpoint#listenerName and removed
org.apache.kafka.network.EndPoint. Certain parts of the code depend on
listener name normalization. We should add a test to make sure there is
no regression.

A new behavior was introduced to junit 5.12
(89a46dfa10),
disallowing `ClusterTestExtensions` to generate empty invocation
contexts. However, `ClusterTestExtensions` is invoked by junit extension
so it could result in empty contexts for some tests.

Move AddPartitionsToTxnManager to server module and convert to Java.
This patch moves AddPartitionsToTxnManager from the core module to the
server module, with its package updated from `kafka.server` to
`org.apache.kafka.server.transaction`. Additionally, several
configuration used by AddPartitionsToTxnManager are moved from
KafkaConfig.scala to AbstractKafkaConfig.java.
- brokerId
- requestTimeoutMs
- controllerListenerNames
- interBrokerListenerName
- interBrokerSecurityProtocol
- effectiveListenerSecurityProtocolMap
The next PR will move AddPartitionsToTxnManagerTest.scala to java

Old bootstrap.metadata files cause problems with server that include
KAFKA-18601. When the server tries to read the bootstrap.checkpoint
file, it will fail if the metadata.version is older than 3.3-IV3
(feature level 7). This causes problems when these clusters are
upgraded.
This PR makes it possible to represent older MVs in BootstrapMetadata
objects without causing an exception. An exception is thrown only if we
attempt to access the BootstrapMetadata. This ensures that only the code
path in which we start with an empty metadata log checks that the
metadata version is 7 or newer.

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.

This PR proposes a switch to enable share groups for 4.1 (preview) and
4.2 (GA).
* `share.version=1` to indicate that share groups are enabled. This is
used as the switch for turning share groups on and off.
In 4.1, the default will be `share.version=0`. Then a user wanting to
evaluate the preview of KIP-932 would use `bin/kafka-features.sh
--bootstrap.server xxxx upgrade --feature share.version=1`.
In 4.2, the default will be `share.version=1`.

This patch is the second of a series of patches to remove the old group
coordinator. With the release of Apache Kafka 4.0, the so-called new
group coordinator is the default and only option available now.
The patch removes `group.coordinator.new.enable` (internal config) and
all its usages (integration tests, unit tests, etc.). It also cleans up
`KafkaApis` to remove logic only used by the old group coordinator.

Move the ClusterTest setup callback to `BeforeEachCallback` instead of
`BeforeTestExecutionCallback`. This allows the setup to happen slightly
earlier and before any `@BeforeEach` methods are invoked.
We cannot inject ClusterInstance into a `@BeforeEach` method, but we can
still use the constructor injection which allows a `@BeforeEach` fixture
to access the ClusterInstance. This enables tests to do some common
cluster setup (like creating topics) before each test case.
No changes were made to `@AfterEach` or our ClusterTest teardown logic.

Split the JUnit tests into "new", "flaky", and the remainder.
On PR builds, "new" tests are anything that do not exist on trunk. They are run with zero tolerance for flakiness.
On trunk builds, "new" tests are anything added in the last 7 days. They are run with some tolerance for flakiness.
Another change included here is that we will not update the test catalog if any test job fails on a trunk build. We have had difficulty determining if all the tests had or not (due to timeout or failures in upstream Gradle tasks). By requiring green ":test" jobs, we can be sure that the resulting catalog will be valid.
---
The purpose of this change is to discourage contributors from adding flaky tests, but give some leeway for trunk so we have successful builds.
The "quarantinedTest" Gradle target has been consolidated into the regular "test" target. There are now some
runtime properties to control what tests are run.
* kafka.test.catalog.file: path to test catalog
* kafka.test.run.new: include new tests. this selection depends on the age of the loaded test catalog
* kafka.test.run.flaky: include tests marked as `@Flaky` (replaces the `excludeTags 'flaky'` directive)
* kafka.test.verbose: include additional logging from new JUnit classes (enabled by default if re-running GitHub workflow with debug logging enabled)
* maxTestRetries: how many retries to allow via Develocity retry plugin (default 0)
* maxTestRetryFailures: how many failures to allow before stopping retries (default 0)
Thanks to Jun Rao for inspiring the idea.

3.3.0 was the first KRaft release that was deemed production-ready and also
when KIP-778 (KRaft to KRaft upgrades) landed. Given that, it's reasonable
for 4.x to only support upgrades from 3.3.0 or newer (the metadata version also
needs to be set to "3.3" or newer before upgrading).
Noteworthy changes:
1. `AlterPartition` no longer includes topic names, which makes it possible to
simplify `AlterParitionManager` logic.
2. Metadata versions older than `IBP_3_3_IV3` have been removed and
`IBP_3_3_IV3` is now the minimum version.
3. `MINIMUM_BOOTSTRAP_VERSION` has been removed.
4. Removed `isLeaderRecoverySupported`, `isNoOpsRecordSupported`,
`isKRaftSupported`, `isBrokerRegistrationChangeRecordSupported` and
`isInControlledShutdownStateSupported` - these are always `true` now.
Also removed related conditional code.
5. Removed default metadata version or metadata version fallbacks in
multiple places - we now fail-fast instead of potentially using an incorrect
metadata version.
6. Update `MetadataBatchLoader.resetToImage` to set `hasSeenRecord`
based on whether image is empty - this was a previously existing issue that
became more apparent after the changes in this PR.
7. Remove `ibp` parameter from `BootstrapDirectory`
8. A number of tests were not useful anymore and have been removed.
I will update the upgrade notes via a separate PR as there are a few things that
need changing and it would be easier to do so that way.

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.

Apache Kafka 4.0 will only support KRaft and 3.0-IV1 is the minimum version supported by KRaft. So, we can assume that Apache Kafka 4.0 will only communicate with brokers that are 3.0-IV1 or newer.
Note that KRaft was only marked as production-ready in 3.3, so we could go further and set the baseline to 3.3. I think we should have that discussion, but it made sense to start with the non controversial parts.

Currently the validation of feature upgrade relies on the supported version range generated during registration. For a given feature, its max supported feature version in production is set to be the default version value (the latest feature version with bootstrap metadata value smaller or equal to the latest production metadata value).
This patch introduces a LATEST_PRODUCTION value independent from the metadata version to each feature so that the highest supported feature version can be customized by the feature owner.
The change only applies to dynamic feature upgrade. During formatting, we still use the default value associated the metadata version.
