> 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.
