[~szetszwo] Thanks for your help! I'll take the new order and change the current implementation of IoTDB. Hope that I can conclude this issue soon.

> GroupMismatchException occurs when I'm trying to start and add a new server to the group.
> Reproduce steps:
>  # call CompletableFuture.supplyAsync(admin().setConfiguration(newGroup))
>  # call groupManagementApi(newServer).add(group)
> GroupMismatchException happens time to time, as in the attched log.
> I think the setConfiguration here may route the request to the NEW server to be added, since it does not explicitly assign a serverId in request. setConfiguration arrives before addNewGroup, so GroupMismatchException happens.
