> Currently, labels on nodes changes will only be handled by RMNodeLabelsManager, but that is not enough upon labels on nodes changes:
> - Scheduler should be able to do take actions to running containers. (Like kill/preempt/do-nothing)
> - Used / available capacity in scheduler should be updated for future planning.
> We need add a new event to pass such updates to scheduler
