Implements deconstruct_keys to enable pattern matching on HTTP responses
based on status code, content type, and other response attributes.
Example:
case response
in code: '200', content_type: /json/
JSON.parse(response.body)
in code: '404'
handle_not_found
end

This was a similar trick as to what we had used around pattern matching for the 2.6 to 2.7 push, so I'm repeating it here. The other methods should function even without syntax bridges like this.
