KAFKA-4677: Avoid unnecessary task movement across threads during rebalance
Makes task assignment more sticky by preferring to assign tasks to clients
that had previously had the task as active task. If there are no clients with
the task previously active, then search for a standby. Finally falling back to
the least loaded client.
