      Currently during preemption, AM is notified with a list of containers which are marked for preemption. Introducing a timeout duration also along with this container list so that AM can know how much time it will get to do a graceful shutdown to its containers (assuming one of preemption policy is loaded in AM).
      This will help in decommissioning NM scenarios, where NM will be decommissioned after a timeout (also killing containers on it). This timeout will be helpful to indicate AM that those containers can be killed by RM forcefully after the timeout.
