python 3.11 required + token/scenario as cmd line arg

Yannickrequested to merge
python_311 into main
  • python 3.11 required (was python 3.10+ before), the main reason is usage of SpooledTemporaryFile to fully implement IOBase abstract so it can be used as data inside aiohttp request in order to reduce memory footprint inside the test client.
  • README updated accordingly
  • add -t/--token and -s/--scenario as command line parameter.
