tripleo-repos on ubi9 generates wrong dlrn repos

[chandan kumar]

While running tripleo-repos on ubi9, it generates following errors:
```
(testing_repos) [root@dc18ffdd1a6b tripleo-repos]# tripleo-repos --stream -b master current-tripleo ceph
WARNING: Centos9 Base and AppStream will be installed for this UBI distro
Traceback (most recent call last):
  File "/tmp/tripleo-repos/testing_repos/bin/tripleo-repos", line 10, in <module>
    sys.exit(main())
  File "/tmp/tripleo-repos/testing_repos/lib64/python3.9/site-packages/tripleo_repos/main.py", line 622, in main
    _install_repos(args, base_path)
  File "/tmp/tripleo-repos/testing_repos/lib64/python3.9/site-packages/tripleo_repos/main.py", line 488, in _install_repos
    content = _get_repo(base_path + 'current-tripleo/delorean.repo',
  File "/tmp/tripleo-repos/testing_repos/lib64/python3.9/site-packages/tripleo_repos/main.py", line 257, in _get_repo
    r.raise_for_status()
  File "/tmp/tripleo-repos/testing_repos/lib64/python3.9/site-packages/requests/models.py", line 1022, in raise_for_status
    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 404 Client Error: Not Found for url: https://trunk.rdoproject.org/ubi9-master/current-tripleo/delorean.repo
```
Below is the steps to reproduce it.
1. podman pull ubi9
2. git clone https://opendev.org/openstack/tripleo-repos
3. podman run --privileged -v <full path to tripleo-repos>:/tmp/tripleo-repos -it 46720ac964ac bash
4. cd /tmp/tripleo-repos
5. python3 -m venv testing_repos
6. source testing_repos
7. pip install requests
8. PBR_VERSION=1.2.3 python3 setup.py install
9. tripleo-repos --stream -b master current-tripleo ceph

above error comes.

The current tripleo-repos lacks the support for the same.

    Fixed the repo generation code for ubi9

    It fixes:
    - Mirror map for ubi9, rhel9
    - fallback to centos(8,9) if ubi(8,9) distros are used.
    - Look for both ubi8 and ubi9 where ubi8 is previously defined.
