Description of problem:

VPA uninstall instructions CLI steps have too many steps and the steps are difficult to perform properly.

I think that the optional step 6 (parts a-h) under https://docs.openshift.com/container-platform/4.11/nodes/pods/nodes-pods-vertical-autoscaler.html#nodes-pods-vertical-autoscaler-uninstall_nodes-pods-vertical-autoscaler should be replaced with something like this:

a. Remove all VPA components

oc delete ns openshift-vertical-pod-autoscaler

b. Remove custom resources and CRDs related to the VPA. Note: this step will cause all user-created VPA objects to be removed from the cluster and any such objects would need to be recreated after a VPA reinstall.
