Swap Flask API for FastAPI

[dgarnitz]

Right now we are running Flask with Gunicorn using PM2. There are a few problems with this:

• Flask is not fast
• PM2 is designed for node JS, not pythonb

We should swap Flask for FastAPI and (if possible in one PR) swap PM2 for something more appropriate.

Note: We currently depend on Flask-sql alchemy for our DB ORM. We will need to swap this when migrating away from Flask. This may also require changes to the DB services that are also dependencies for the worker and vdb upload worker

Also FastAPI have an awesome automatic documentation generation :

Hi @dgarnitz, I was trying to maintain the abstraction of the request to get API Keys and files. I am having issues with handling the files. This is sample representation of the file "<_io.BufferedReader name='api/tests/fixtures/test_text.txt'>"

Also with this approach we will lose better auto docs generation support

@datgerhardt Can you provide me with more context around the bug you ran into? Perhaps some screenshots or a code snippet

Thanks for your patience, I had the Internet outage in Ghana due to a problem with undersea cable for past few weeks
