uvicorn swallows exceptions from h11

[sschnabe]

For requests with large headers (above 16kb) h11 throws an exception in h11/_connection.py#L488. This exception is catched in uvicorn/protocols/http/h11_impl.py#L178 and the log line Invalid HTTP request received. is logged. The error with useful message from h11 is hidden. I would expect the exception is logged so i can see why the request was invalid.

Should i create an issue and/or pr?

PS: i know i can increase the header buffer with --h11-max-incomplete-event-size

I think ideally, we would show more information on a different level.

We had a exc_info parameter in the past: #1518
