Explore async

Shepherd is usally used by a single user at a time yet there are probally still benifits to be gained by sprinkling async everywhere.

Not sure if this requires us to do anything fancy with FastAPI.

DONE IS:

• Evaluate weather its worth it to do this
• Maybe do it

Async will probably have benefits, I have used async with fastapi before and unless you are trying to start fastapi from async code it is not an issue

Sounds good, not super urgent right now but maybe something we can do in the future
