Before these changes the request tracing was added for each route
registered using the routing.RouteRegister, see code. This had the
consequence that middleware executed earlier/later in the request
pipeline was not part of the request tracing middleware life-cycle
which measures the duration of requests among other things.
In the logger middleware we do extract the current distributed trace
identifier, if available, and set that on request info/error log messages.
With these changes we can extract the current distributed trace identifier,
if available, and set that on the contextual HTTP request logger
(models.ReqContext.Logger) which would improve the possibility to correlate
all HTTP request log messages with traces.
In addition, the request tracing middleware is now executed first and last in
the request pipeline and should therefore result in more accurate timing
measurements (request duration).
