Add qos rule type filtering

Added two new filter flags to ``openstack network qos rule type list``:
- "--all-supported", to return any QoS rule type supported by at least
  one loaded driver.
- "--all-rules", to return all QoS rule types supported by the current
  version of Neutron server, regardless of the loaded drivers.
