Rack shutdown issues

Problem statement: A rack shutdown in a multi-rack HA setup can cause the Backup & Restore service to go to an unknown state.

Resolution: In the case of a rack shutdown, if a graceful shutdown is not working or the node is in a non-recoverable state, you can manually add an out-of-service taint on the node. For more information about how it works, see Kubernetes Blogs.
Remove the taint on the affected node after the node is recovered.
