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.

This change adds the upgrade documentation for 3.6.0 and fixes the position of the notable changes in 3.5.0.
In previous releases, notable changes always come after the upgrade instructions.
Reviewers: Luke Chen <showuon@gmail.com>, Satish Duggana <satishd@apache.org>
In KIP-778 we introduced the "unsafe" (lossy) downgrade in case metadata has changes in one of the versions between target and current, as defined in MetadataVersion.
The documentation says it is possible:
"Note that the cluster metadata version cannot be downgraded to a pre-production 3.0.x, 3.1.x, or 3.2.x version once it has been upgraded. However, it is possible to downgrade to production versions such as 3.3-IV0, 3.3-IV1, etc."
The command line tool shows that this doesn't work:
bin/kafka-features.sh --bootstrap-server :9092 downgrade --metadata 3.4 --unsafe
Could not downgrade metadata.version to 8. Invalid metadata.version 8. Unsafe metadata downgrade is not supported in this version.
1 out of 1 operation(s) failed.
In addition to unsafe, also safe metadata downgrades are not supported in practice. For example, when you upgrade to 3.5, you land on 3.5-IV2 as metadata version, which has metadata changes and won't let you to downgrade. This is true for every other release at the moment.
This change fixes the documentation to reflect that, and improves the error messages.

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.

This change does the following:
1. Make RemoteLogManagerConfigs that are implemented public
2. Add tasks to generate html docs for the configs
3. Include config docs in the main site
Reviewers: Divij Vaidya <diviv@amazon.com>, Luke Chen <showuon@gmail.com>, Christo Lolov <lolovc@amazon.com>, Satish Duggana <satishd@apache.org>
This implementation introduces two new configurations `log.message.timestamp.before.max.ms` and `log.message.timestamp.after.max.ms` and deprecates `log.message.timestamp.difference.max.ms`.
The default value for all these three configs is maintained to be Long.MAX_VALUE for backward compatibility but with the newly added configurations we can have a finer control when validating message timestamps that are in the past and the future compared to the broker's timestamp.
To maintain backward compatibility if the default value of `log.message.timestamp.before.max.ms` is not changed, we are assuming users are still using the deprecated config `log.message.timestamp.difference.max.ms` and validation is done using its value. This ensures that existing customers who have customized the value of `log.message.timestamp.difference.max.ms` will continue to see no change in behavior.

Fixed a regression described in KAFKA-15053 that security.protocol only allows uppercase values like PLAINTEXT, SSL, SASL_PLAINTEXT, SASL_SSL. With this fix, both lower case and upper case values will be supported (e.g. PLAINTEXT, SSL, SASL_PLAINTEXT, SASL_SSL, plaintext, ssl, sasl_plaintext, sasl_ssl)

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.
