> Unlike the LeaderAndIsrRequest, the StopReplicaRequest does not include the
> leader epoch which makes it vulnerable to reordering. This KIP proposes to
> add the leader epoch for each partition in the StopReplicaRequest and the
> broker will verify the epoch before proceeding with the StopReplicaRequest.
