[service-announce] Removing fedora-30 nodes from Nodepool and Zuul

The OpenDev team is planning to remove the fedora-30 node label from Nodepool and Zuul in the near future. Fedora 30 has been EOL for a couple months now and we have Fedora 32 nodes we want to get people onto. Before this can happen one of the things we need to do is bump the fedora-latest nodeset from fedora-30 to fedora-32. We plan to make this change to fedora-latest on September 22, 2020.

If you use the fedora-30 label direction (not via fedora-latest) it would be great if you can start switching to fedora-32 or fedora-latest instead. Once we've removed these uses of the label we'll remove the image entirely from Nodepool and Zuul.
