Introduce support for CentOS 9 Stream.
Verified host can be deployed using oVirt 4.5.0 with CentOS Stream 9 using non UEFI BIOS (due to https://bugzilla.redhat.com/show_bug.cgi?id=2081648) once updated libnl3-3.6.0-2.el9 from https://kojihub.stream.centos.org/koji/buildinfo?buildID=18351 (should land on centos stream mirrors soon).
Moving back to modified, after all on CentOS Stream 9 bug #2091581 is not relevant. For RHEL 9 we'll document how to get the missing package.
