      Description

      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.
