docs: Serializer for native falcon HTTPError exceptions.
  
          We override the default serializer with our own so we
          can ensure the errors are serialized in a JSON API
          compliant format.
  
          Surprisingly, most falcon error attributes map directly
          to the JSON API spec. The few that don't can be mapped
          accordingly:
  
  
              HTTPError               JSON API
              ~~~~~~~~~               ~~~~~~~~
  
              exc.description    ->   error['detail']
              exc.link['href']   ->   error['links']['about']
  
  
          Per the falcon docs this function should return a tuple
          of (MIMETYPE, BODY PAYLOAD)
