Motivation

This is a followup to KIP-154 and KIP-464.

The configuration for Kafka Connect distributed worker currently requires several configuration properties that define the names of the three internal Kafka topics that the workers will use for storing connector configs, offsets, and statuses:

The allowed values for the following existing Connect distributed worker properties will be changed to also allow -1 to signal that the broker's default replication factor should be used for the newly created topics:

...

These additional properties (without the prefix) will be passed to the new topic requests created by the Connect worker when it attempts to create the internal topics.

Proposed Changes

When the Connect distributed worker starts up, it currently attempts to create the configuration, offsets, and/or status topics used by the worker if any of those topics do not exist. With this proposal, the additional properties will be passed to the broker during these new topic requests. Note that like with KIP-154, these properties will not be used if the corresponding topic already exists.
