Manually install github3 dependency in zuul
Manually install github3 dependency in zuul

Until we have sigmavirus/github3.py#671 in a release we will have to
handle this manually. Unfortunately pip install . doesn't handle git
links in requirements.txt files and so we do it in the deployment
instead.
