…up/failover (apache#373) TICKET = LIKAFKA-44768 LI_DESCRIPTION = Enhance timing-related logging for Kafka controller startup/failover, minimizing performance impact as much as possible. In particular, the extra logging focuses on (Zk)ReplicaStateMachine, which previous logging has identified as a particular hotspot, and only when switching more than 250,000 replicas to OnlineReplica mode. EXIT_CRITERIA = If and when this change is accepted upstream and pulled into this repo.

StreamThread should keep calling consumer.poll() even when no task is assigned. This is necessary to get a task.
