Pull request to implement KIP-1111, aims to add a configuration that
prevents a Kafka Streams application from starting if any of its
internal topics have auto-generated names, thereby enforcing explicit
naming for all internal topics and enhancing the stability of the
application’s topology.
- Repartition Topics:
All repartition topics are created in the
KStreamImpl.createRepartitionedSource(...) static method. This method
either receives a name explicitly provided by the user or null and then
builds the final repartition topic name.
- Changelog Topics and State Store Names:
There are several scenarios where these are created:
In the MaterializedInternal constructor.
During KStream/KStream joins.
During KStream/KTable joins with grace periods.
With key-value buffers are used in suppressions.

This PR covers all the docs for KIP-1112, including the new config and a note about the new APIs in the 4.0 section of the upgrade guide.
This also fixes/updates some unrelated parts of the upgrade guide that were out-of-date, such as the broker compatibility matrix

- StreamsConfig#RETRIES_CONFIG was deprecated in AK 2.7 and is no longer in use.
- StreamsConfig#DEFAULT_WINDOWED_KEY_SERDE_INNER_CLASS and
- StreamsConfig#DEFAULT_WINDOWED_VALUE_SERDE_INNER_CLASS were deprecated in AK 3.0.
Reviewers: Chia-Ping Tsai <chia7712@gmail.com>
All public interface changes should be briefly mentioned in the
upgrade guide.

Configs default.windowed.value.serde.inner and default.windowed.key.serde.inner
were replace with windowed.inner.class.serde. This PR updates the docs accordingly,
plus a few more side cleanups.

There is an overlap between two sections in the current version of streams-config.html as described in KAFKA-14404.
The goal of this fix is to remove the overlap as well as describing some other parameters and their default values

Documentation only—Minor clarification on how max.warmup.replicas works; specifically, that one "warmup replica" corresponds to a Task that is restoring its state. Also clarifies how max.warmup.replicas interacts with probing.rebalance.interval.ms.

This PR is part of a series implementing the self-join rewriting. As part of it, we decided to clean up the TOPOLOGY_OPTIMIZATION_CONFIG and make it a list of optimization rules. Acceptable values are: NO_OPTIMIZATION, OPTIMIZE which applies all optimization rules or a comma separated list of specific optimizations.

#10813 changed the default serde from ByteArraySerde as discussed in KIP-741. This adds proper documentation so users know to set a serde through the configs or explicitly pass one in.

Code samples are now unified and correctly formatted.
Samples under Streams use consistently the prism library.

Deprecates the following
1. StreamsConfig.EXACTLY_ONCE
2. StreamsConfig.EXACTLY_ONCE_BETA
3. Producer#sendOffsetsToTransaction(Map offsets, String consumerGroupId)
And introduces a new StreamsConfig.EXACTLY_ONCE_V2 config. Additionally, this PR replaces usages of the term "eos-beta" throughout the code with the term "eos-v2"

During the AK website upgrade, changes made to kafka-site weren't migrated back to kafka-docs.
This PR is an attempt at porting the streams changes to kafka/docs
For the most part, the bulk of the changes in the PR are cosmetic.

- part of KIP-572
- removed the usage of `retries` in `GlobalStateManger`
- instead of retries the new `task.timeout.ms` config is used
Reviewers: John Roesler <john@confluent.io>, Boyang Chen <boyang@confluent.io>, Guozhang Wang <guozhang@confluent.io>
Add docs for KIP-441 and KIP-613.
Fixed some miscellaneous unrelated issues in the docs:
* Adds some missing configs to the Streams config docs: max.task.idle.ms,topology.optimization, default.windowed.key.serde.inner.class, and default.windowed.value.serde.inner.class
* Defines the previously-undefined default windowed serde class configs, including choosing a default (null) and giving them a doc string, so the yshould nwo show up in the auto-generated general Kafka config docs
* Adds a note to warn users about the rocksDB bug that prevents setting a strict capacity limit and counting write buffer memory against the block cache
