Single node jobs are failing on this error message:

{  fail [github.com/openshift/origin/test/extended/single_node/topology.go:97]: pod-identity-webhook in openshift-cloud-credential-operator namespace expected to have 1 replica but got 2
Expected

This started happening after https://github.com/openshift/cloud-credential-operator/pull/492 merged, the number of replicas should be dependent on the cluster topology (HA or single node).
