Description

When elector elects RM to become active, even though RM is already in ACTIVE state AdminService does refresh on following configurations.

1. refreshAdminAcls
2. refreshAll to update the configurations.

But ideally even these operations are need NOT to be done and can be skipped refreshing configurations on ACTIVE RM. However admin executes refresh command separately if there is any config changes to be done.
