This feature adds maintenance burden and potential security concerns
while providing no apparent value to the Kafka community. See

In KRaft, custom KafkaPrincipalBuilder instances must implement
KafkaPrincipalSerde to support the forward mechanism. Currently, this
requirement is not enforced and relies on the developer's attention.
With this patch, we can prevent incorrect implementations at compile
time.

Add a note to the upgrade documentation indicating that
`remote.log.manager.thread.pool.size` has been deprecated. Users should
now use `remote.log.manager.follower.thread.pool.size` instead.

This is the initial documentation for KIP-932 preview in AK 4.1. The aim
is to get very minimal docs in before the cutoff. Longer term, more
comprehensive documentation will be provided for AK 4.2.
The PR includes:
* Generation of group-level configuration documentation
* Add link to KafkaShareConsumer to API docs
* Add a summary of share group rational to design docs
* Add basic operations information for share groups to ops docs
* Add upgrade note describing arrival of KIP-932 preview in 4.1

As part of KIP-1043, `Admin.listConsumerGroups()` and variants have been
deprecated. This is because there are now 4 types of group and listing
has been consolidated under `Admin.listGroups()`. This PR adds the
deprecation information to the upgrade documentation.

The `window.size.ms` and `window.inner.class.serde` are not a true
KafkaStreams config, and are ignored when set from a KStreams
application. Both belong on the client.

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

Add new section for Kafka 4.0 compatibility metrics for user, so user

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
the following error. This PR fixes the issue by adding the required
argument.
`kafka-features: error: one of the arguments --bootstrap-server
--bootstrap-controller is required.`
Reviewers: Colin P. McCabe <cmccabe@apache.org>
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).

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)

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.
Reviewers: Ismael Juma <ismael@juma.me.uk>
This patch introduces a new page to document the configs and metrics that have been removed in the transition to 4.0. While these removed items lack a formal deprecation cycle as they are part of KIP-500, KIP-500 itself does not provide an exhaustive list of all impacted configs and metrics. Therefore, this new page aims to assist Kafka users in understanding the specific configs and metrics that have been removed in the 4.0 release.

KIP-863 introduced a change to ByteBufferDeserializer which is not
