Simple logging middleware that captures the following: * remote address (whether proxied or direct) * if authenticated, then user email address * request method (GET/POST etc) * request full path * response status code (200, 404 etc) * content length * request process time * If DEBUG=True, also logs SQL query information - number of queries and how long they took
