Markos Chandras e4456ed4c1 Use a venv with previous ansible version for upgrades
When doing the role upgrade, we run every playbook with current's
branch ansible. This is normal for the infrastructure bits (which
are running on current branch), but not for the installation of
the previous branch's role, which should use previous branch's
environment.
