OTA-420 and https://github.com/openshift/cluster-version-operator/pull/617 added logic to all resources managed by CVO. However some resources like ClusterOperator are not updated once they are created. So their ownerReferences will be not be updated/set when the newer version of CVO is rolled out.

To fix this, create only objects should also have their ownerReferences set if they are not already set. The value does not need to be ever updated after it is set because the resource will be garbage collected if the clusterversion is deleted.
