Added support for filtering the QoS rule type list command.
Two new filter flags are added:
- all_supported: if True, the listing call will print all QoS rule
types supported by at least one loaded mechanism driver.
- all_rules: if True, the listing call will print all QoS rule types
supported by the Neutron server.
Both filter flags are exclusive and not required.
