Description

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.
