CentOS has published the official mirror for CentOS Stream 9 [1]. In RDO,
we are working to get ready for it ASAP and we have the required repos
to run p-o-i on CS9 [2].
This patch is adding support to CS9 in p-o-i repo with the required
fixes. Also is adding integrations jobs for scenarios 0-4 and adding
them as non-voting. Note that we don't have promotion pipeline working
so i think it's better to not make it voting yet.
