http.route SHOULD include application root

[trask]

What are you trying to achieve?

Clarity that "application root" SHOULD be included in http.route (in cases where there is an application root).

There is language in the HTTP tracing spec which implies it may or may not be:

Given an inbound request for a route (e.g. "/users/:userID?") the name attribute of the span SHOULD be set to this route.
If the route does not include the application root, it SHOULD be prepended to the span name.

I'd like to remove this sentence:

If the route does not include the application root, it SHOULD be prepended to the span name.

and instead add a note to the http.route definition that "it SHOULD include the application root (if there is one)"
