Remove route from response errors

[davidporos92]

Motivation

The response_errors also included the route label, which can lead to a lots of data. This is pretty similar to #65

What

Removes the route from the response_errors. Also, I've updated the readme to align with the current responses.

Why

Avoid creating an excessive number of metrics.
