> Should use equals when compare Resource in RMNodeImpl#ReconnectNodeTransition 
> to avoid unnecessary NodeResourceUpdateSchedulerEvent.
> The current code use {{!=}} to compare Resource totalCapability, which will 
> compare reference not the real value in Resource. So we should use equals to 
> compare Resource.
