Hello. I prepare PR that implements `ReplicationQuotasTestRig` in java - https://github.com/apache/kafka/pull/14588 Please, review.
PR contains screenshots and reports both from scala version and java version [1] So It seems pretty straightforward. PR that rewrites `ReassignPartitionCommand` to java successfully landed in trunk. But, we have one postponed dependency that must be rewritten in java - `ReplicationQuotasTestRig` which is application in tests that run locally and produces some charts for reassign process.
