The task-level commit metrics were removed without deprecation in KIP-447 and the corresponding PR #8218. However, we forgot to update the docs and to remove the code that creates the task-level commit sensor.
This PR removes the task-level commit metrics from the docs and removes the code that creates the task-level commit sensor. The code was effectively dead since it was only used in tests.

Some users complained they don't have a way to determine if there is something wrong in the RSM plug-in they implemented, or there's something wrong in Kafka itself. Also, if there are users who just want to try the tiered storage feature out before implementing anything, it would be good we have an RSM implementation by default.
Per the discussion in the KIP, there will be no default RSM implementation in Kafka, but we can use the LocalTieredStorage implemented for integration test, to resolve the issues above.

I've added details for VerificationFailureRate and VerificationTimeMs.
I considered adding the documentation for the AddPartitionsToTxnVerification metrics, but I noticed that all the request metrics simply listed Produce|FetchConsumer|FetchFollower. If we don't already report the AddPartitionsToTxn request metrics in this file, it doesn't make sense to add the verification variant. (As well as all the other APIs we report)
Filed a followup jira if we want to redo that whole section.

In "ZooKeeper to KRaft Migration" documentation, we are still reporting 3.4 as metadata version. Reworking that phrase to make it more clear and avoid the need to update it in the future.

Most of the contents in the README.md was already covered in the docs therefore only had to add the section for Exactly Once support.

Currently, the current-state KRaft related metric reports follower state for a broker while technically it should be reported as an observer as the kafka-metadata-quorum tool does.

This is the PR for the implementation of KIP-847: https://cwiki.apache.org/confluence/display/KAFKA/KIP-847%3A+Add+ProducerIdCount+metrics
Add ProducerIdCount metric at the broker level:
kafka.server:type=ReplicaManager,name=ProducerIdCount
Added unit tests below to ensure the metric reported the count correctly.

This PR adds some RocksDB metrics that could not be added in KIP-471 due to RocksDB version. The new metrics are extracted using Histogram data provided by RocksDB API, and the old ones were extracted using Tickers. The new metrics added are memtable-flush-time-(avg|min|max) and compaction-time-(avg|min|max).

During the AK website upgrade, changes made to kafka-site weren't migrated back to kafka-docs.
This PR is an initial attempt at porting the changes to kafka/docs, but it does not include the streams changes. Those will come in a separate PR.
For the most part, the bulk of the changes in the PR are cosmetic. Only the introduction.html has substantial changes, but it's a direct port from the live documentation.
For testing:
I reviewed the PR diffs
Rendered the changes locally
