Instrumentation.Http-1.8.0

OpenTelemetry.Instrumentation.Http

• Fixed an issue for spans when server.port attribute was not set with
  server.address when it has default values (80 for HTTP and
  443 for HTTPS protocol).
  (#5419)

• Fixed an issue where the http.request.method_original attribute was not set
  on activity. Now, when http.request.method is set and the original method
  is converted to its canonical form (e.g., Get is converted to GET),
  the original value Get will be stored in http.request.method_original.
  The attribute is not set on .NET Framework for non canonical form of CONNECT,
  GET, HEAD, PUT, and POST. HTTP Client is converting these values
  to canonical form.
