Added port-resource-request-groups API extension, that provides support for
the new format of port's ``resource_request`` and
``binding:profile.allocation`` attributes. The new format allows to request
multiple groups of resources and traits from the same RP subtree.
Assigning a new ``QoS policy`` with ``minimum_packet_rate`` rule to an
``already bound port`` updates the allocation in Placement.
``NOTE``: Placement allocation update is not supported if original QoS
policy had no ``minimum_packet_rate`` rule. Changing from direction-less
``minimum_packet_rate`` rule to a direction-oriented
``minimum_packet_rate`` rule is not supported.
