Subject: QoS service plugin stub
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=2ff19be1db96f97b833052af633abda55f497f1d;p=openstack-build%2Fneutron-build.git

QoS service plugin stub

This patch introduces the QoS service plugin which implements
a stub of the API extension.

This is patch is a basic step to be able to create an experimental
job enabling this service so we can do api tests.
