[internal] Responses Design

Responses (response.py)

FailureResponse

FailureResponse must take in an error_code, nice_message, and debug_message in its __init__ method. Please ensure that the response uses camel case keys in the response itself (not the Python class).

FailureResponse must implement a method called as_json() which will convert the provided data into json via the json.dumps() method.

FailureResponse must, lastly, implement a method called response() which will return flask's make_response(self.as_json(), self.error_code). If possible, this function may also take in a headers dictionary and update the response headers before returning it.

FailureResponse must also implement logging on a call to response().
