If someone chooses to run under uwsgi/apache instead of eventlet, the
basic logging of requests goes away (as that was an eventlet.wsgi
function). This is a critical piece of information for understanding
how services are working, and we need to retain it under uwsgi/apache.
This creates a new request_log middleware, inspired by the one in
placement, to provide that functionality. This includes all the same
information as before: http method, uri, status, content length, time
for the request. It also includes the microversion the request was
processed as, "-" if no microversion.
The middleware does not emit anything if it detects that it's running
under eventlet, to prevent duplicate log messages.
Release notes provided as this will be a manual transition for folks
as it's an api-paste.ini change.
