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

[KIP-962](https://cwiki.apache.org/confluence/display/KAFKA/KIP-962%3A+Relax+non-null+key+requirement+in+Kafka+Streams)
The key requirments got relaxed for the followinger streams dsl operator:
left join Kstream-Kstream: no longer drop left records with null-key and call ValueJoiner with 'null' for right value.
outer join Kstream-Kstream: no longer drop left/right records with null-key and call ValueJoiner with 'null' for right/left value.
left-foreign-key join Ktable-Ktable: no longer drop left records with null-foreign-key returned by the ForeignKeyExtractor and call ValueJoiner with 'null' for right value.
left join KStream-Ktable: no longer drop left records with null-key and call ValueJoiner with 'null' for right value.
left join KStream-GlobalTable: no longer drop records when KeyValueMapper returns 'null' and call ValueJoiner with 'null' for right value.

KIP-914 introduced a new boolean isLatest into Change to indicate whether a change update represents the latest for the key. Even though Change is serialized into the table repartition topic, the new boolean does not need to be serialized in, because the table repartition map processor performs an optimization to drop records for which isLatest = false. If not for this optimization, the downstream table aggregate would have to drop such records instead, and isLatest would need to be serialized into the repartition topic.
In light of the possibility that isLatest may need to be serialized into the repartition topic in the future, e.g., if other downstream processors are added which need to distinguish between records for which isLatest = true vs isLatest = false, this PR reserves repartition topic formats which include isLatest. Reserving these formats now comes at no additional cost to users since a rolling bounce is already required for the upcoming release due to KIP-904. If we don't reserve them now and instead have to add them later, then another bounce would be required at that time. Reserving formats is cheap, so we choose to do it now.

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.

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.
