Thank you [~sunilg] for review comments
Extremely sorry for confusing earlier with the comment of introducing contains interface

> We should add again to ordering policy only when  attempt available in first case.Else
during application attempt removal will try to iterate on killed application still available
in pending Ordering policy.Which can cause RM to crash.
