I think by default, infra runs jobs with python2. This is the job 
definition for openstack-tox-pep8 [0] which says it "Uses tox with the 
``pep8`` environment." And in our tox.ini [1], we don't specify the 
basepython version. I contrasted the openstack-tox-pep8 job definition 
with the tempest-full-py3 job definition [2] and it sets the 
USE_PYTHON3=True variable for devstack.

So, I think we're not gating the pep8 job for python3, only python2, and 
that's how the problems got through the gate in the first place. I'm not 
sure what the best way is to fix it -- whether we should be looking at 
adding a base openstack-tox-pep8-py3 job to openstack-zuul-jobs that 
sets USE_PYTHON3=True or if we need to instead change something in our 
tox.ini or what.
