I think Ihar has already been working on this, i.e.

https://github.com/openstack/neutron-lbaas/commit/acdb72f70c4ce5d096353851889d8497c2ed32a4

I think this only impacts the periodic stable job because of how the job works and how the tools/tox_install.sh script works.

And he has a project-config change here:

It's now fixed in liberty for all *aas repos.
