> Today, scheduler is tied to attempt only.
> We need to separate app-level handling logic in scheduler. We can add new 
> app-level events to the scheduler and separate the app-level logic out. This 
> is good for work-preserving AM restart, RM restart, and also needed for 
> differentiating app-level metrics and attempt-level metrics.
