Load balancer deploy fails if OCP not installed

Error:

"error retrieving cluster Infrastructure resource: failed to get API group
resources: unable to retrieve the complete list of server APIs:
config.openshift.io/v1: the server could not find the requested resource"

The code checks apierrors.IsNotFound however this doesn't handle if the
CRD isn't installed. Use admiral's resource.IsNotFoundErr instead.
