need to be installed, we make use of the following ansible modules:

1. pip: we install python3-pip python3-setuptools virtualenv
   as per https://docs.ansible.com/ansible/latest/modules/pip_module.html

   `apt show virtualenv` Depends: python3, python3-virtualenv
   `apt show python3-virtualenv` Depends: python-pip-whl (>= 8.1.1-2), python3, python3-distutils, python3-pkg-resources
