> Ideally, the NM should wait for a limited amount of time when it gets a shutdown signal
for existing containers to complete and kill the containers ( if we pick an aggressive approach
) after this time interval. 
> For NMs which come up after an unclean shutdown, the NM should look through its directories
for existing container.pids and try and kill an existing containers matching the pids found.
