> RMAppImpl has a DUMMY_APPLICATION_RESOURCE_USAGE_REPORT to return when the caller of createAndGetApplicationReport doesn't have access.
> RMAppAttemptImpl should have something similar for getApplicationResourceUsageReport.
> It also might make sense to put the dummy report into ApplicationResourceUsageReport and allow both to use it.
> A test would also be useful to verify that RMAppAttemptImpl#getApplicationResourceUsageReport doesn't return null if the scheduler doesn't have a report to return.
