Add support for minimum packet rate rule to the client7.7.0

With the introduction of QoS minimum packet rate rule in Neutron,
it's important to ensure that tools like Heat support it as well.
Unfortunately, Heat still depends on python-neutronclient instead
of python-openstackclient. So even though QoS minimum packet rate
rule support have been proposed for python-openstackclient [1] and
openstacksdk [2], it's still necessary to extend python-neutronclient
code. Since Heat uses only the client part, can skip CLI support.
