Addressing Dan's comments. This changeset provides: - improved framework for API versioning, with separated controllers for each API version - Taken from nova:'Resource' class in WSGI framework. This class is a container for serializers, deserializers and controller - Better deserialization thanks to resource class. _parse_request_params has been removed - Improved management of HTTP client errors NOTE: this changeset does not update the framework used by API extensions.
