[help-wanted] Implement an adapter to run Python wsgi based applications

At the moment we mostly deploy "functions", however many python applications are wsgi servers (flask and fastapi for example)

It is possible to implement an adapter that can run wsgi based applications as functions so you can deploy as functions many microframework applications

The issue names no files, tests, or entry points. Start by locating the existing function adapters and Python runtime path, then compare the WSGI callable model used by Flask and FastAPI. Done means a WSGI-based Python application can be deployed and run as a function.
