Yum Add Repo
------------
**Summary:** add yum repository configuration to the system

Add yum repository configuration to ``/etc/yum.repos.d``. Configuration files
are named based on the dictionary key under the ``yum_repos`` they are
specified with. If a config file already exists with the same name as a config
entry, the config entry will be skipped.

**Internal name:** ``cc_yum_add_repo``

**Module frequency:** per always

**Supported distros:** fedora, rhel

**Config keys**::

yum_repos:
        <repo-name>:
            baseurl: <repo url>
            name: <repo name>
            enabled: <true/false>
            # any repository configuration options (see man yum.conf)
