URL: https://github.com/apache/kafka/pull/7916
This is a docs only PR. Added documentation about specifying log_dirs inline with KIP-113 and updated example json schemas to include new "log_dirs" field examples.
*Summary of testing strategy (including rationale)
for the feature or bug fix. Unit and/or integration
tests are expected for any behaviour change and
system tests should be considered for larger changes.*

> KIP-113 introduced support for moving replicas between log directories. As part of it, support was added to kafka-reassign-partitions.sh so that users can move replicas between log directories. Specifically, when you call "kafka-reassign-partitions.sh --topics-to-move-json-file topics-to-move.json", you can specify a "log_dirs" key in the topics-to-move.json file, and kafka-reassign-partitions.sh will then move those replicas to those directories.
>
> However, when working on that KIP, we didn't update the docs on kafka.apache.org to describe how to use the new functionality. We should add documentation on that.
>
> I haven't used it before, but whoever works on this Jira can probably figure it out by experimentation with kafka-reassign-partitions.sh, or by reading KIP-113 page or the associated JIRAs.
