RedHat Subscription
-------------------
**Summary:** register red hat enterprise linux based system

Register a RedHat system either by username and password *or* activation and
org. Following a sucessful registration, you can auto-attach subscriptions, set
the service level, add subscriptions based on pool id, enable/disable yum
repositories based on repo id, and alter the rhsm_baseurl and server-hostname
in ``/etc/rhsm/rhs.conf``. For more details, see the ``Register RedHat
Subscription`` example config.

**Internal name:** ``cc_rh_subscription``

**Module frequency:** per instance

**Supported distros:** rhel, fedora

**Config keys**::

rh_subscription:
        username: <username>
        password: <password>
        activation-key: <activation key>
        org: <org number>
        auto-attach: <true/false>
        service-level: <service level>
        add-pool: <list of pool ids>
        enable-repo: <list of yum repo ids>
        disable-repo: <list of yum repo ids>
        rhsm-baseurl: <url>
        server-hostname: <hostname>
