Jean-Philippe Evrard f1144a762c 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.

# PURPOSE:
# This script executes test Ansible playbooks required for performing
# an upgrade test of the os_neutron role.
# Due to the way Ansible caches and handles modules, we need to run
# separate Ansible runs to ensure the "upgrade" uses the new
# "neutron_migrations_facts" module, instead of the cached version
# used when deploying the previous Neutron version.
