    Add uselist=True to subnet rbac_entries relationship

    Because the join conditions for Subnet rbac entries
    are manually specified, SQLAlchemy is not
    automatically detecting that this relationship is a list.
    This adds the uselist=True kwarg to the relationship to
    ensure that it's always handled as a list.
