> 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.
