Submit before_record_interaction to VCRpy to replace CleanYAMLSerializer

[zdc217]

Discussing with @ddriddle:

The CleanYAMLSerializer code is a work around for before_record_response to allow us to access the request to match the URI. Should we consider contributing code to VCRpy that adds access to the request to the before_record_response param?

Another approach might be to add something like before_record_interaction that would give access to the response and the request.

Per team discussion, Ed approves and we should do this

Similar issues have been submitted. We could potentially close those out by contributing this code to VCRpy
