Return the raw HTTP response

[alazaro]

In some cases you don't need to get any of the elements of the JSON object, but the object itself. I couldn't find the way to do that so I introduced a very small modification to the MiniJsonExtractor. If no key is specified, the whole object will be returned.

I see what you're doing here, and agree there's a use case. There's a better way to do this though: define a RawBodyExtractor. This way it works with any response (not necessarily just JSON), and it doesn't require unexpected behavior from the MiniJsonExtractor (which one would expect to fail with an empty query).

See the Extensions Guide.
This can be a core extractor, so you'll add a definition to the registry in validators.py

Code will be something like this + tests (not tested, yet).

class RawBodyExtractor(AbstractExtractor):
    """ Extractor that pulls out a named header """
    extractor_type = 'raw_body'  # Printable name for the type
    is_header_extractor = False  # Use headers in extraction
    is_body_extractor = True  # Uses body in extraction

    def extract_internal(self, query=None, args=None, body=None, headers=None):
        """ Return the HTTP response
        """
        return body

    @classmethod
    def parse(cls, config, extractor_base=None):
        return RawBodyExtractor()

Implemented in: b06b72e

With extractor name 'raw_body"

@alazaro It turns out that other users were also looking for this feature, and found some significant use cases that did require the full root JSON document, so I've gone ahead and added it (currently on the master branch), in addition to the raw body extractor.
