Description of problem: When running something like oc patch dc registry-console -p '{"spec":{"template":{"spec":{"nodeSelector":{"role":"infra"}}}}}' several times in a row, oc always informs '"registry-console" patched' even though no changes were made.
Please check if patched field's name/level is correct, seems it should be "selector" rather than "nodeSelector" See https://bugzilla.redhat.com/show_bug.cgi?id=1409225#c3
