http_response: status_code match

Required for all PRs:

• Signed CLA.
• Associated README.md updated.
• Has appropriate unit tests.

I've added the possibility to match on the status code instead of only the response body, can be useful if your service return a 204.

I'm not fully satisfied because actually we can only check the body OR the status code (not both). Technically isn't difficult to be able to do both, but that require some decisions about the result value, if only one of these fail the value is pretty obvious but in case both check fail, do we need to create another value (response_mismatch?) or set the field to response_status_code_mismatch or response_string_mismatch

Thanks!

would it make more sense to instead just record the status code, instead of a binary match/no-match?

The status code is already record under http_response_code
