Require specifying a driver image on OpenShift 4.12 with 25.3.1 or later.

25.3.1 has introduced a breaking change on OpenShift 4.12 (still supported by Red Hat).
The symptom is driver daemonset pods entering CrashLoopBackOff. The user must now
expicitely specify a supported driver image in ClusterPolicy, instead of relying on the default image.
