[2224076] Newly added API endpoints for virtualmachineinstances broke openshift-restclient-python

Description of problem: Four API endpoints were added recently: https://github.com/kubevirt/kubevirt/blame/9cf6dbb3e33c9ec9e9af8b18eb115c7fb9f7c311/pkg/virt-operator/resource/generate/rbac/cluster.go#L45-49. They broke openshift-restclient-python, which expects these end points to be of the format <a>/<b>
https://github.com/openshift/openshift-restclient-python/blob/master/openshift/dynamic/discovery.py#L133

This would block all test runs as we use openshift-restclient-python indirectly in cnv-tests for all api calls via openshift-python-wrapper.

Version-Release number of selected component (if applicable):
4.15.0

How reproducible:
100%

Steps to Reproduce:

This would block all T2/smoke tests against 4.15.0
