Rename ClusterRoles created by OperatorGroups

When an OperatorGroup creates a ClusterRole, it's based directly on the
OG name with a suffix, this causes two issues:
1. same-named OGs in different namespaces overwrite each others CRs
2. there are some very important CRs that could be overwritten by OG

Tests added.
