> 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.
