Move RHEL branch to TMT

Advantages:
- Test RHEL branches on on actual RHEL
- Reduce our GCE/AWS usage
- Easier to switch git host (RE: CNCF)

The spec file is fetched from CentOS Stream as it's publicly available
and the RHEL branches are most often close enough, if not identical.

Fixes: RUN-3105
