> When a nodemanager shuts down it needs to determine if it is likely to be restarted.
 If a restart is likely then it needs to preserve container directories, logs, distributed
cache entries, etc.  If it is being shutdown more permanently (e.g.: like a decommission)
then the nodemanager should cleanup directories and logs.
