@zhangshuyan0 @ZanderXu @tasanuma @tomscut Hi, sir. Have updated this PR.
1. Only move the single high priority command to the head of queue. The
left commands in cmds are processed as usually.
2. iterate the cmds which are from heartbeat response reversely.
> CommandProcessingThread#queue should use LinkedBlockingDeque to prevent high
> priority command blocked by low priority command
