Subject: [PATCH] Rehome functions to enable Neutron's QoS service

Those functions were part of the neutron devstack plugin but we
discussed it during last PTG [1] and decided to move to the Devstack
repo plugins which are used by e.g. CI jobs which are defined outside
of the neutron repository.
QoS service is used e.g. in the tempest-slow job which is
defined in tempest and used by many different OpenStack projects.
