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.

The table of (stateless) transformations uses the transformation name in the first column and a description in the second column. I adjusted the transformation name for FlatMapValues accordingly.

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.

Prior to this commit FK response sink routed FK results to
SubscriptionResolverJoinProcessorSupplier using the primary key.
There are cases, where this behavior is incorrect. For example,
if KTable key serde differs from the data source serde which might
happen without a key changing operation.
Instead of determining the resolver partition by serializing the PK
this patch includes target partition in SubscriptionWrapper payloads.
Default FK response-sink partitioner extracts the correct partition
from the value and routes the message accordingly.

In the RocksDb memory management doc, we mentioned in the footnote that there's a rocksdb bug caused the strict_capacity_limit boolean parameter in the LRUCache constructor can't be set to true. However, the bug is already fixed in 6.11.4, and we're using 6.22 now, so the note can be removed.
Reviewer: Bruno Cadonna <cadonna@apache.org>
Right now, we have scattered uses of `SerDes` throughout the docs. These should be updated to be `Serdes`, as that's what we commonly use now.

Implementation of KIP-744.
Creates new Interfaces for TaskMetadata, ThreadMetadata, and
StreamsMetadata, providing internal implementations for each of them.
Deprecates current TaskMetadata, ThreadMetadata under o.a.k.s.processor,
and SreamsMetadata under a.o.k.s.state.
Updates references on internal classes from deprecated classes to new interfaces.
Deprecates methods on KafkaStreams returning deprecated ThreadMeatada and
StreamsMetadata, and provides new ones returning the new interfaces.
Update Javadocs referencing to deprecated classes and methods to point
to the right ones.

Quick followup to KIP-740 to actually deprecate this constructor, and update the upgrade guide with what we changed in KIP-740. I also noticed the TaskId#parse method had been modified previously, and should be re-added to the public TaskId class. It had no tests, so now it does

Part of KIP-572: follow up work to PR #9800. It's not save to retry a TX commit after a timeout, because it's unclear if the commit was successful or not, and thus on retry we might get an IllegalStateException. Instead, we will throw a TaskCorruptedException to retry the TX if the commit failed.

During the AK website upgrade, changes made to kafka-site weren't migrated back to kafka-docs.

Reviewers: A. Sophie Blee-Goldman <sophie@confluent.io>, Guozhang Wang <wangguoz@gmail.com>
Wildcard import of the old org.apache.kafka.streams.scala.Serdes leads
to a name clash because some of implicits has the same names as types
from the scala's std lib. The new oak.streams.scala.serialization.Serdes is
the same as the old Serdes, but without name clashes.
The old one is marked as deprecated.
Also, add missing serdes for UUID, ByteBuffer and Short types in
the new Serdes.
Implements: KIP-616

- part of KIP-572
- removed the usage of `retries` in `GlobalStateManger`
- instead of retries the new `task.timeout.ms` config is used

- part of KIP-572
- deprecates producer config `retries` (still in use)
- deprecates admin config `retries` (still in use)
- deprecates Kafka Streams config `retries` (will be ignored)
- adds new Kafka Streams config `task.timeout.ms` (follow up PRs will leverage this new config)
Reviewers: John Roesler <john@confluent.io>, Jason Gustafson <jason@confluent.io>, Randall Hauch <randall@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
