Description

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
