3. execute the delete , could see not delete the graph-image :
curl http://localhost:5000/v2/openshift/graph-image/tags/list | jq
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

{
  "name": "openshift/graph-image",
  "tags": [
    "latest"
  ]
}

 the graph-delete should not delay on the local cache, should be able to delete the mirror2mirror mode.
