`transform` and `through` are removed in 4.0. Since users cannot
reference them in 4.0 document, it's not good to keep using them as
example in `repartition` description.

Currently, the "Notable changes in 4.0.0" for the client is very confusing. We should remove it.

In "Upgrading to 4.0.0 from any version 0.8.x through 3.9.x" section, we
directly give instructions about [Upgrading to KRaft-based
clusters](https://kafka.apache.org/documentation/#upgrade_390_kraft),
but there might still be some users under ZK cluster before upgrading to
v4.0.0. We need to make it clear that they need to upgrade to KRaft mode
first before upgrading to v4.0.0 in "Upgrading to 4.0.0 from any version
0.8.x through 3.9.x" section.

Running `bin/kafka-features.sh upgrade --release-version 4.0` results in

Add information about setting dynamic log levels and dynamic

Reviewers: Ismael Juma <ismael@juma.me.uk>, Chia-Ping Tsai <chia7712@gmail.com>
Using `bin/kafka-features.sh upgrade --metadata 4.0` to finalize the
upgrade is deprecated and furthermore it does not bump all the other
feature flags. Hence we should recommend to use `bin/kafka-features.sh
upgrade --release-version 4.0` in the documentation. This change was
introduced in [KIP-1022: Formatting and Updating
Features](https://cwiki.apache.org/confluence/display/KAFKA/KIP-1022%3A+Formatting+and+Updating+Features).

… must check topic describe (#18989)
This patch filters out the topic describe unauthorized topics from the
ConsumerGroupHeartbeat and ConsumerGroupDescribe response.
In ConsumerGroupHeartbeat,
- if the request has `subscribedTopicNames` set, we directly check the
authz in `KafkaApis` and return a topic auth failure in the response if
any of the topics is denied.
- Otherwise, we check the authz only if a regex refresh is triggered and
we do it based on the acl of the consumer that triggered the refresh. If
any of the topic is denied, we filter it out from the resolved
subscription.
In ConsumerGroupDescribe, we check the authz of the coordinator
response. If any of the topic in the group is denied, we remove the
described info and add a topic auth failure to the described group.
(similar to the group auth failure)

Link to the older version of the documentation for people who care about
the old message format.
Reviewers: Jun Rao <junrao@apache.org>, Chia-Ping Tsai <chia7712@apache.org>
Details:
1. Upgrades to 4.0.x are only supported from 3.3.x and for kraft mode clusters
2. Add rolling upgrade instructions for 4.0.x
3. Clarify the message for zk to kraft migrations
4. Remove all the upgrade instructions for older versions (they can still be found in the upgrade notes for older releases)
Reviewers: Chia-Ping Tsai <chia7712@gmail.com>, David Jacot <djacot@confluent.io>
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.

Most of the changes are obvious clean-ups/fixes. A couple of noteworthy items:
1. Support for non LTS versions is clarified (we were incorrectly stating full support
for Java 23).
2. TLS version negotiation details are clarified.
Reviewers: Matthias J. Sax <matthias@confluent.io>, Chia-Ping Tsai <chia7712@gmail.com>
This patch changes the default value of `group.coordinator.threads` to `4` and sets it priority to `HIGH`. This change makes it consistent with how we handle `num.network.threads` and `num.io.threads`. The patch also tweaks the upgrade notes.

This PR upgrades RocksDB from 7.9.2 to 9.7.3 and addresses the following compatibility issues introduced by the RocksDB upgrade:
- Removal of AccessHint: The AccessHint class was completely removed in RocksDB 9.7.3. This required removing all import statements, variable declarations, method parameters, method return types, and static method calls related to AccessHint in RocksDBGenericOptionsToDbOptionsColumnFamilyOptionsAdapter.java RocksDBGenericOptionsToDbOptionsColumnFamilyOptionsAdapterTest.java Unused methods are removed in RocksDBGenericOptionsToDbOptionsColumnFamilyOptionsAdapter.java
- Removal of NO_FILE_CLOSES: The NO_FILE_CLOSES metric was also removed in RocksDB 9.7.3. The calculation for numberOfOpenFiles in RocksDBMetricsRecorder.java has been adjusted to now track the total number of file opens since the last reset. The previous calculation, which subtracted NO_FILE_CLOSES from NO_FILE_OPENS, is no longer possible. The reason RocksDB removed NO_FILE_CLOSES seems to be that it did not properly work: https://github.com/search?q=repo%3Afacebook%2Frocksdb+NO_FILE_CLOSES&type=issues
- Removal of methods related to compressed block cache configuration in BlockBasedTableConfig
- Change of the signature of org.rocksdb.Options.setLogger()
