> We proposed non-exclusive node labels in YARN-3214, makes non-labeled
> resource requests can be allocated on labeled nodes which has idle resources.
> To make preemption work, we need know an allocated container's original node
> label: when labeled resource requests comes back, we need kill non-labeled
> containers running on labeled nodes.
> This requires add node-labels in Container, and also, NM need store this
> information and send back to RM when RM restart to recover original container.
