Section Number and Name:

6.5.2. Uninstalling OpenShift Virtualization by using the CLI

Describe the issue:

The CLI method should also remove the namespace `openshift-cnv` as a last step. This makes sure that all the related objects are deleted. Following the current steps will end up in below orphan objects:

~~~

1. oc get secret -n openshift-cnv
   NAME TYPE DATA AGE
   builder-dockercfg-nvw9k kubernetes.io/dockercfg 1 3h30m
   builder-token-kkk96 kubernetes.io/service-account-token 4 3h30m

   kubemacpool-service kubernetes.io/tls 2 3h27m
   plugin-serving-cert kubernetes.io/tls 2 3h27m

1. oc get cm -n openshift-cnv
   NAME DATA AGE
   cdi-apiserver-signer-bundle 1 3m39s

This can cause issues in installing the operator back where CDI operator will fail because of the above orphan secret and configmap objects.
