Stop supporting python2

OpenStack Infra is running Zuul v3 on Python3. We're adding things, like
the websockets streaming, that are python3 only - and testing them turns
out to be extra hard even with skipTest because of the syntax changes.
There are no legacy Zuul v3 installations to worry about, and the
Software Factory team has verified that Python3 on CentOS 7 is not a
problem. It's time to pull the plug.

Remove python2 jobs from running in v3. Make the tox defaults python3
for all testenvs and update setup.cfg to indicate that Zuul v3 supports
python3 and not python2.

Also fixed a python3 bug in zuul command line client that shows up
when running zuul --help under python3.
