Automatic redacting

[soffes]

I know VCR does this. We should copy them. Manually redacting cassettes is pretty tedious.

@soffes I'd be interested in implementing this functionality, can you elaborate upon what you're looking to have redacted?

I have a PR in my fork of this that adds this functionality, based on VCR.py.

It allows you to specify header, query or post body filters (though I haven't implemented POST body) which can be of three types:

• .remove - removes the key/value pair from the interaction
• .replace(String) - replaces the value with the specified one (useful for putting "redacted")
• .closure((String, String) -> (String?)) - runs a closure that takes in the key/value pair and either returns the new value or nil to omit.
