Dispatch this request if this is a request to a reserved URL.

        If the request matches one of our reserved URLs, this calls
        start_response and returns the response body.  This also handles OPTIONS
        CORS requests.

        Args:
          request: An ApiRequest, the request from the user.
          start_response: A function with semantics defined in PEP-333.

        Returns:
          None if the request doesn't match one of the reserved URLs this
          handles.  Otherwise, returns the response body.
