In Neutron in patch I75bd18b3a1875daa5639dd141fb7bbd6e1c54118
list of supported_rules was changed from list of rule types to
dict with rule types and available parameters and values.
Additionally parameter `direction` was introduced for
qos_bandwidth_limit rule type in Neutron in
Ia13568879c2b6f80fb190ccafe7e19ca05b0c6a8
By default each rule has got EGRESS direction so this value of
direction is supported by existing qos_driver.
