> when a consumer sends OffsetCommitRequest, it also can be treated as a 
> Heartbeat and the `GroupCoordinator` will invoke 
> `completeAndScheduleNextHeartbeatExpiration`  to update the expires when 
> handleCommitOffsets. 
> so we can also update the heartbeat expires of ConsumerCoordinator when send 
> OffsetCommitRequest to reduce Heartbeat Request.
