Enchancement: better control of loggers

[vsoch]

Currently, when we start with four (or more) workers, we see the equivalent in logging:

It looks like there is a way to remove the root logger (that passes on to the workers) and just use one logger tiangolo/fastapi#1508 (comment). It's not huge priority because it's mostly aesthetic, but if someone wants to grab this (before I do) that would be great!

okay closer inspection I think flux is doing this - when I run with N>1 workers just locally (without flux start) I don't see any issue.

[vsoch]

Transferred to operator - this seems to be an artifact of flux start being given uvicorn. I can't reproduce running uvicorn with the server alone.

I think this is resolved. It would be good to parse apart the timing logs from the job logs, but that's for another day.
