    Add new subordinate relation for domain backends

    Support configuration of domains via suboridnate charms that
    implement the new 'keystone-domain-backend' relation type; these
    charms will create domain specific configuration files in
    /etc/keystone/domains, and will notify the keystone charm when
    configuration is complete, and the domain is ready for creation
    in the keystone database.

    Subordinate charms can also request a restart of keystone by
    setting or changing the value of the 'restart-nonce' key in the
    relation.
