    Add internal_info field to ports and portgroups

    In case of ports, it is also added to the API, as a readonly field.
    It will be used for any port-specific internal information ironic
    needs to store inside the port object. In this change we start using
    it to store UUIDs of the cleaning ports that ironic creates, instead
    of fiddling with port.extra['vif_port_id'], as extra is intended for
    operator use only.
