    Align rhel custom files with upstream (#1431)

    So far RHEL had its own custom .service and cloud.cfg files,
    that diverged from upstream. We always replaced the generated files
    with the ones we had.

    This caused only confusion and made it harder to rebase and backport
    patches targeting these files.
    At the same time, we are going to delete our custom downstream-only files
    and use the ones generated by .tmpl.

    The mapping is:
    config/cloud.cfg.tmpl -> rhel/cloud.cfg
    systemd/* -> rhel/systemd/*

    Such rhel-specific files are open and available in the Centos repo:
    https://gitlab.com/redhat/centos-stream/src/cloud-init

    With this commit, we are also introducing modules in cloud.cfg that
    were not in the default rhel cfg file, even though they should already
    have been there with previous rebases and releases.
    Anyways such modules support rhel as distro, and
    therefore should cause no harm.
