KAFKA-4843: More efficient round-robin scheduler - Improves streams efficiency by more than 200K requests/second (small 100 byte requests) - Gets streams efficiency very close to pure consumer (see results in https://jenkins.confluent.io/job/system-test-kafka-branch-builder/746/console) - Maintains same fairness across tasks - Schedules all records in the queue in-between poll() calls, not just one per task.
