New way of validation of QoS policy can be applied on port/network based on
port_types. It can validate if port can support rule by rule_type and also by
rule parameters or some values of parameters.
For example bandwidth_limit_rule can have parameter "direction" with
possible values "ingress" and "egress". Some of mechanism drivers can support
only one of those directions.
If user will try to apply policy with rule unsupported by port_type then it
will get error message and policy will not be applied.
Such validation is made during:
* port create
* port update
* network update
* QoS rule create
* QoS rule update
