KAFKA-15307: Removes non-existent configs

[Cerchie]

addresses 1/3 of https://issues.apache.org/jira/browse/KAFKA-15307

Removes pieces of configuration from the developer guide to configuring streams..

These were the pieces of configuration not found in StreamsConfig.java.

They include:

• partition.grouper
• rack.aware.assignment.tag
• rocksdb.config.setter
• state.dir
• topology.optimization

Note: acks and replication.factor, although not found in 'StreamsConfig.java', are listed in the developer guide to configuring streams. I am assuming they are defined somewhere else.

Committer Checklist (excluded from commit message)

• Verify design and implementation
• Verify test coverage and CI build status
• Verify documentation (including upgrade notes)

Thanks for the PR. I know that we did remove partition.grouper, but the others seems to be valid config. For example https://github.com/apache/kafka/blob/trunk/streams/src/main/java/org/apache/kafka/streams/StreamsConfig.java#L665

Can you double check again?

huh. I wonder if was working from an un-updated fork-- double-checking.

EDIT: update-- just double-checked and replaced the configs that were not missing. It was only partition.grouper that needed removal.
