> We need add preemption info to RM web page to make administrator/user get 
> more understanding about preemption happened on app, etc. 
> And RM logs should have following properties:
> * Logs are retrievable when an application is still running and often flushed.
> * Can distinguish between AM container preemption and task container 
> preemption with container ID shown.
> * Should be INFO level log.
