Subscription support

[tw]

In the wiki you mention that it's not supported yet.

Is it desired/anyone working on it? It's something I'd like - and might be able to start work on at some point.

Hi @tw,

I don't really know what is demand for subscriptions, but I guess it would be really nice addition to KGraphQL. I'm almost sure nobody is working on it, so feel free to start!

Do you already have any ideas/intial design? I would love to hear them.

@pgutkowski thanks for the response. I myself would like them so I could start to consider using it at work (we're currently using graphql-java, I'd like something a bit smaller, and more native).

I suppose I'd probably use a combination of coroutines/channels to handle subscriptions - especially now co-routines are non-experimental.
