    Description

      Currently, in KafkaController.checkAndTriggerAutoLeaderRebalance(), we call onPreferredReplicaElection() one partition at a time. This means that the controller will be sending LeaderAndIsrRequest one partition at a time. It would be more efficient to call onPreferredReplicaElection() for a batch of partitions to reduce the number of LeaderAndIsrRequests.
