CentOS Stream 9 based nodes have been included in nodepool
configuration. This patch is adding centos9 jobs in check pipeline for
packstack project.
It's also implementing some changes required for CS9:
- Setting mkisofs as mkisofs_cmd which is alias for genisoimage in cs8
and to xorriso in cs9.
- It enable repo crb and remove redhat-lsb-core package which is not
longer included inc cs9.
- We are forcing to run puppet with LANG=C.UTF-8. In CS9, LANG variable
is not longer being forwarded in ssh connection so we need to force
viable UTF-8 character set anc C.UTF8 is always available [1].
Until we have a proper promotion pipeline for centos9 I'll keep the jobs
as non-voting and only in check pipeline.
