Add Ability to filter responses by status code

[cedricbahirwe]

I have created a simple filter for status code as requested in https://github.com/pmusolino/Wormholy/issues/122.

I added a simple implementation that leverages as much as possible the existing source code and still achieves the result in a simple and clean way.

I am looking forward to your feedback.
