limit-request-line errors are not logged

For example when url is too long, gunicorn will respond with 400 and a short html, but access or error logs are not written.
This makes it harder to diagnose an issue when all you have is server side metrics/logs.

There are debug logs but debug level is too noisy to enable in production.

Does it make sense to add access/error/exception logging to handle_error for this class of issues?

[benoitc]

maybe a warning without the exception?

[sergeypeloton]

Yeah that would work.
