> When the NM is shutting down with restart support enabled there are scenarios we'd like
to distinguish and behave accordingly:
> # The NM is running under supervision.  In that case containers should be preserved so
the automatic restart can recover them.
> # The NM is not running under supervision and a rolling upgrade is not being performed.
 In that case the shutdown should kill all containers since it is unlikely the NM will be
restarted in a timely manner to recover them.
> # The NM is not running under supervision and a rolling upgrade is being performed. 
In that case the shutdown should not kill all containers since a restart is imminent due to
the rolling upgrade and the containers will be recovered.
