Python Version Support

Zuul v3 requires Python 3. It does not support Python 2.

As Ansible is used for the execution of jobs, it's important to note that while Ansible does support Python 3, not all of Ansible's modules do. Zuul currently sets ansible_python_interpreter to python2 so that remote content will be executed with Python 2.
