      Description of problem:

      After unmanaging a cluster via ZTP by removing the siteconfig and resources file from gitops, the "open-cluster-management-addon-observability" namespace and objects running in the namespace are still there. I would expect all things to be cleaned up after a cluster is no longer managed by the hub.

      # oc get managedcluster vm00002
Error from server (NotFound): managedclusters.cluster.open-cluster-management.io "vm00002" not found
# oc --kubeconfig /root/hv-vm/kc/vm00002/kubeconfig get po -n open-cluster-management-addon-observability
