The environment executing the test playbooks matters. Establish a
script to bootstrap a known-good and fixed-version python virtual
environment. Spell out precise execution requirements in a standard
pip 'requirements.txt' file, including version numbers and hashes.
Upon executing the ``venv-ansible-playbook.sh`` wrapper, a virtual
environment is setup and contained within a fixed (or temporary)
directory, with full logs from setup. If this is to be preserved
across executions, the ``$WORKSPACE`` environment variable must be
set and exported beforehand.
