Add ROOT_PATH to config, pass it through to FastAPI

• allows FastAPI to handle stripping the base url for incoming requests

Hi @mgeplf,

I randomly saw this change and from what I remember it might not work as you expect. You can read about this in this SO article.

In short, the app with a custom root_path still expects the path to be stripped by the proxy, which is not exactly our case, Application Load Balancer is passing requests as is without doing so.

For some other services I see the option 1 was used, e.g.: Virtual Lab API (see the BASE_PATH param).

I hope that helps.

Interesting, thanks for noticing.
I have a load balancer that is close to what is in production, in my sandbox, and the change seems to work there.
We shall see when I get this stuff deployed in prod.
