refactor: sort ClusterRole rules by apiGroups, resources

[erikgb]

Description

This is the next in line towards resolving #204. Since controller-gen is sorting the RBAC rules by apiGroups, then resources, I think it is safest if we do the sorting as a pre-PR before migrating to generating the clusterrole. Please let me know if you can think of a more review-friendly approach...

Next PR before migrating to generating will be yaml lists formatting.
