> Currently, AbstractFetcherThread has a series of protected APIs which control access to the Leader. ReplicaFetcherThread and ReplicaAlterLogDirsThread respectively override these protected APIs and handle access to the Leader in a remote broker leader and a local leader context.
> We propose to move these protected APIs to a LeaderEndPoint interface, which will serve all fetches from the Leader. We will implement a RemoteLeaderEndPoint and a LocalLeaderEndPoint accordingly. This change will greatly simplify our existing follower fetch code.
