Option to remove quotes for keys in printer about circe

[travisbrown]

Thanks, @chandu0101, but I'm a little hesitant to add this to core, for a few reasons:

1. The result isn't valid JSON. In some cases circe can be configured to be more conservative than the JSON spec (e.g. it can maintain insertion order), but not less.
2. If we did decide to support this syntax on the printing side, I'd prefer to support parsing it, and that's likely to be a lot more complicated.
3. I know practically nothing about GraphQL, but at a glance it looks like it adds other syntax to JSON that isn't covered by this change (so you still can't use circe to produce arbitrary GraphQL).

Does this sound accurate? If there's demand for this, and if we can add parsing support (not necessarily using Jawn), I'd definitely consider including it in a new module.

first of all thanks for prompt and detailed response

End of the story, i thought its a valid JSON :(

Yeah GraphQL is JSON like query lang but its API'S(js clients) accepts valid js.Object's, looks like i am calling API in wrong way even though it works!. I think i actually need Json to scala.js js.Object/js.Dynamic which we can cover in #93 !
