      Description

      Do retry in FileSystemRMStateStore for better error recovery when update/store failure due to IOException.
      When we use FileSystemRMStateStore as yarn.resourcemanager.store.class, We saw the following IOexception cause the RM shutdown.

      As discussed at YARN-1778, TestFSRMStateStore failure is also due to IOException in storeApplicationStateInternal.

      It will be better to Improve FileSystemRMStateStore to do retry for better error recovery when update/store failure
