Public bug reported:

Currently Neutron has API call "qos-available-rule-types" which will return subset of pos rules supported by all loaded drivers (openvswitch, linuxbridge, etc.)
After https://bugs.launchpad.net/neutron/+bug/1586056 was closed it's not enough and some changes should be done with it.
1. qos-available-rule-types should return subset of rules supported by ANY of loaded drivers, not by all drivers. This should be changed because now if rule is supported by at least on of drivers than it can be used and applied to ports bound with this driver. Neutron will not allow to apply such rule to other ports.
2. Some new API call should be added to report details about supported rules. It should returns something like

+--------+---------------------+----------------------------+
| Driver | Supported rule      | Supported parameters       |
+--------+---------------------+----------------------------+
| ovs    |bandwidth_limit_rule | direction: egress          |
|        |                     | max_kbps: ANY VALUE        |
+--------+---------------------+----------------------------+
| LB     |bandwidth_limit_rule | direction: egress, ingress |
|        |                     | max_kbps: ANY VALUE        |
+--------+---------------------+----------------------------+

Thanks to that API call operator will be able to discover exactly which
rules and with what values can be applied to ports bound with specific
driver.
