Also Fix zuul breakage
pip install started failing back in May.
The zuul/zuul project seems to have caused the problem
Also Fix linting by updating Zuul action plugin path
Previously Zuul hosted the zuul_return action plugin in a path ending in
actiongeneral/; however, as of Zuul v6 this path is simply action/.
Update linting config to use the current and working path.
