502 Bad gateway in html format

[codebien]

Kong version: 0.6.0

If upstream is unreachable Nginx returns a bad gateway response in HTML format. IMO a JSON response would be better.

Thank you for this great product!

This will require a configuration change and can land in 0.7.0. I will work on it.

I would be nice if one could configure an error page per API. Maybe even per status code and having a catch all. Of course if those pages fail, one could still show the current error page, but it would at least allow a little bit more customisation.

Once this issue is closed, a next iteration on the feature could include what @elruwen is suggesting. I opened #972 to keep track of this.

Thanks!
