This question is pretty dated, but I had the same error accuring on the Debian Stretch release auf Openstack Neutron. I solved the problem by deleting qos from the service_plugins in /etc/neutron/neutron.conf.
It now looks like this: service_plugins = router,metering
After restarting the service the command neutron ext-list showed the desired result.
