Register a domain you control with netki as a Gem-managed domain.
        Note: After registering a domain, unless you have already set up its
        DNSSEC/DS Records, you'll need to do so: http://docs.netki.apiary.io
        The information required will be an attribute of the returned NetkiDomain
        object.

        Args:
          domain_name (str): Domain to add (e.g. 'gem.co')
          partner_id (str, optional): your netki partner_id (if you have one)

        Returns: The new round.NetkiDomain
