* ``wsgi_website`` role

  * Dropped support for Python 2.7. Only Python 3 is supported now.

    The ``python_version`` role parameter has been dropped. The

    ``python_interpreter`` parameter is still available, but it

    defaults to Python 3 binary.

    Python (input) requirements files are now placed under the

    ``/etc/pip_check_requirements_upgrades`` path, in accordance to

    changes made in this release to the ``common`` role.
