Check if reload can be done via SIGHUP, or forward --reload flag.

Hey @Kludex,
I want to help with this issue since having this would make Uvicorn obsolete for local dev for me (probably) 😄

SIGHUP can be used to reload workers but as far as I understand, every worker has a reloader instance and sending SIGHUP from the reloader would send multiple signals to the master process if #workers > 1.

I know that Uvicorn itself doesn't support multiple workers when using --reload, is this something that we would want to enforce for local dev then?

Otherwise, what's wrong with this solution that you previously proposed? encode/uvicorn#1193
