Separate guncorn and http loggers.
Because gunicorn has a different syntax for the log format than Python, it wasn't a good idea to update the default log format of http logger to be gunicorn compatible since there is Python code that uses that logger in REST code.
I think we should separate out the logger for gunicorn and revert http to the original python log format, although, it would be a breaking change for some. Currently, you will see invalid key t
related errors from http logger, which can be confusing to users.
