This removes an indirect dependency on jsonify which is unlicensed and not needed in supported environments. Doesn't yet slim down the installed size as ajv has the same dependency. A PR in its repo is also open ajv-validator/ajv#579

What changes did you make? (Give an overview)

Replaced json-stable-stringify with json-stable-stringify-without-jsonify. The modules are identical except for the dependency on jsonify.

Is there anything you'd like reviewers to focus on?

An alternative would be to use nickyout/fast-stable-stringify. I chose not to do so because I'm not sure if eslint can guarantee that there's never a circular dependency.

Thanks for PR. Looks reasonable to me. I just wonder if we should wait for the change to happen in ajv first, before merging this in?

[kaicataldo]

It makes sense to me to wait until ajv is updated and we can do both at once, but I'd also be fine with merging this now as long as we have a way to track/remember that we want to update ajv as well.

@ilyavolodin @kaicataldo ajv 5.3.0 has been released. That version removes the dependency on json-stable-stringify.

@realityking thank for the comment! I created a PR( #9557 ) to upgrade ajv@5.3.0
