> If we submit a app and the number of running app in its corresponding leaf queue has reached its max limit, the app will be put into 'nonRunnableApps'. And its runnabiltiy will only be updated when removing a appattempt(FairScheduler will call `updateRunnabilityOnAppRemoval` at that time).
> Suppose there are only service apps running, they will not finish, so the submitted app will not be scheduled even we change leaf queue's max limit. I think we need update apps' runnability when reloading allocation files for FairScheduler.
