> Currently, we move rmDispatcher out of ActiveService. But we still register the Event
dispatcher, such as schedulerDispatcher, RMAppEventDispatcher when we initiate the ActiveService.
> Almost every time when we transit RM from Active to Standby,  we need to initiate the
ActiveService. That means we will register the same event Dispatcher which will cause the
same event will be handled several times.
