KIP-455 and KAFKA-8345 add a protocol and AdminAPI that will be used for replica reassignments. We need to update the reassignment tool to use this new API rather than work with ZK directly.
Add integration testing ensuring that the reassignment tool can change replication quota with rebalance in progress
Convert ./bin/kafka-reassign-partitions.sh to use KIP-455
