HTTP span name isn’t compliant with the OTel spec

          Just documenting the `HTTP_ROUTE` and span name behavior from upstream

they pull the route off the rpcMetadata here
and set the span name based on this (if defined) here
and here is a route they set during the test which is checked here

Gonna revert the route/span name stuff for now in the interest of having a cleaner PR here, but just wanted to document this somewhere with some links for a convenient reference point.
