Hello. I prepared a PR to move `ConsumerGroupCommand` to `tools` module. Full changes are pretty huge [1] so I split them into several PR’s.
Please, take a look at first PR in the series - https://github.com/apache/kafka/pull/14856 PR adds `ConsumerGroupCommandOptions` class and other command case classes to `tools` module. [1] https://github.com/apache/kafka/pull/14471
