    Uncouple lbaas object models from neutron core plugin results

    Since I6e1ef53d7aae7d04a5485810cc1db0a8eb125953, subnets have
    'description' field. We should accommodate for it on lbaas side.

    Instead of introducing yet another field for lbaas object, make base
    class filter out unknown fields in from_dict() before passing them into
    __init__.
