      Quay caches information about tags for about a minute. OCI conformance tests check that deleted tags are not present in the tag list, and it fails because of the caching.

      Steps to reproduce:

      QUAY_CREDS=quay:password
      QUAY_HOSTNAME=localhost:8080
      QUAY_REPO=quay/test
      
      skopeo copy --dest-tls-verify=false --dest-creds="$QUAY_CREDS" --override-os=linux docker://busybox docker://$QUAY_HOSTNAME/$QUAY_REPO
      skopeo delete --tls-verify=false --creds="$QUAY_CREDS" docker://$QUAY_HOSTNAME/$QUAY_REPO
      skopeo list-tags --tls-verify=false --creds="$QUAY_CREDS" docker://$QUAY_HOSTNAME/$QUAY_REPO

      Expected output:

      {
          "Repository": "localhost:8080/quay/test",
          "Tags": []
      } 

      Actual output:

      {
          "Repository": "localhost:8080/quay/test",
          "Tags": [
              "latest"
          ]
      }
