Denis Buliga 7fc79f43dc Refactors QosAgentDriver
QosAgentDriver has a method which uses linux specific module, which
is trying to import pyroute2.

Module pyroute2 tries to import a module from socket which does not
exists on windows (socket.inet_pton[1]). This can cause neutron
services to fail to start on windows[2].
