Description

RM will store app attempt in both state store and RMAppImpl. YARN-3480 removes attempts that are beyond max-attempt limit from state store.  In this issue we delete those attempts in RMAppImpl the reduce decrease memory usage of RM.

We introduce flag yarn.resourcemanager.am.delete-old-attempts.enabled to enable this logic, default value is false.
