> To support work-preserving NM restart we need to recover the state of the containers
that were active when the nodemanager went down.  This includes informing the RM of containers
that have exited in the interim and a strategy for dealing with the exit codes from those
containers along with how to reacquire the active containers and determine their exit codes
when they terminate.
