MAR-33: Added initial scaffolding for wsgi_website tests:
- Added Molecule configuration file.
- Implemented test playbook that sets-up three separate instances of WSGI
website in order to test all variations of parameters.
- Added name for the set_fact task.
- Fixed linting errors related to mode that lacks leading zero.
- Added skip_ansible_lint tag for command that creates the Python virtual
environment.
- Added missing become keyword wherever become_user is specified.
- Fixed invalid parameter name for specifying if HTTPS should be enforced or
not.
- Added small initial sample WSGI apps that get deployed.
- Added static/media sample files.
- Added TLS material.
- Added initial dummy test file.
- Added Molecule configuration file.
