Enabling cluster wide user permissions to clone data volumes across namespaces

Issue

Attempting to clone a Persistent Volume Claim (PVC) for a virtual machine disk across different namespaces in OpenShift fails with an "insufficient permissions" error. This is due to the namespace-scoped nature of default RBAC rules. The Red Hat documentation shows how to grant permissions for a specific source and destination namespace, but this does not scale for cluster-wide cloning.
