adds structure for virtual environment uwsgi and http communication

- starts uwsgi and flask in virtual environment instead of docker
- sets oauth2 https error to false (OAUTHLIB_INSECURE_TRANSPORT=1)

- this setup works, but
  - moving it into docker
  -  removing the venv
  -  and allowing https connection internally?
would be better
