> ReplicaManager!becomeLeaderOrFollower handles the LeaderAndIsr request,
> StateChangeLogger logs when this request is handled, however it can be useful
> to log when this calls ends and record the time taken, can help
> operationally.
> Proposal is to ReplicaManager!becomeLeaderOrFollower start measuring the time
> before the `replicaStateChangeLock` is acquired and log before the response
> is returned.
