Pushing bona fide status

[opqdonut]

Using the python template from #2512, implement a script that reacts to approved events (For a given resource? By the bona fide bot?) and pushes bona fide status to Elixir.

Approved push spec is very simple: we just pass the elixir-id as an URL parameter and that's it:
https://perun.elixir-czech.cz/rems/?elixirid={elixir_user_id}

The script should:

• react to application/approved events
• look up applicant user id from event/application, key application/applicant
• POST to https://perun.elixir-czech.cz/rems/?elixirid={elixir_user_id} with configurable authentication
• test with bona-fide-bot, needs a decider with a ResearcherStatus visa
  • developer tests with other profile (google login)
  • to be tested on Rahti with Mikael, demo also, see next step
    • fix authentication issue first
• set up on the demo instance with mail server configured
  • https://rems-bona-fide-test.rahtiapp.fi is used
  • ask Valtteri for details setting up the container
