Version-Release number of selected component (if applicable):
OLM: 4.1.6 (release-4.1)

How reproducible:
always

Steps to Reproduce:
1. Deploy ClusterRole/ClusterRoleBinding to the cluster first manually
2. Deploy operator that attempts to create the same ClusterRole/ClusterRoleBinding
3. Observe panic and crash loop in catalog-operator pod

Actual results:
Crash looping catalog-operator pod

Expected results:
catalog-operator is able to re-label ClusterRole/ClusterRoleBinding and continue


Additional info:
Proposed fix for master branch(4.2): https://github.com/operator-framework/operator-lifecycle-manager/pull/959

This will also require backporting a fix to release branches, as the github.com/operator-framework/operator-lifecycle-manager/pkg/controller/operators/catalog package was changed in a substantial way in https://github.com/operator-framework/operator-lifecycle-manager/pull/892
