          Issue Type: Bug

This issue was observed while deploying Ozone with Ratis, with appendEntriesAsync {{AppendEntryRequestProto}} are sent to the followers in an asynchronous manner. It can happen that the follower is replying to the Leader even after the election is over.

{code}
         server.appendEntriesAsync(request).thenCombine(previous,
              (reply, v) -> {
              responseObserver.onNext(reply);
            current.complete(null);
{code}
