The periodic-stable/networking-bagpipe/stable/queens/openstack-tox-py27
job filed with[1]:

    ERROR! /home/zuul/src/git.openstack.org/openstack/networking-bgpvpn not found

As did[2], [3] and [4]

I understand that using zuul-cloner isn't supported but switching to
tox-siblings hasn't happened yet in the mean time I assume this job
failed as stable/queens wasn't listed under branches.

So I admit I'm taking a wild guess here.
