convert to backend plugin

[retzkek]

Backend plugins are the way forward for datasources, and enable alerting among other features. It does mean splitting the codebase between Go and TypeScript, which is good (I'm more comfortable with Go) and bad (more people can contribute to JS/TS, added complexity).

Should start with a newly-generated plugin, which should also fix that pesky build issue (#17).

Hi @retzkek, is there any update on this? We'd love to contribute to the migration in order to allow alerting on graphQL data.

Sorry @nbuchwitz I haven't had a chance to start on this. I appreciate the offer, I'll try to get a basic framework started in the next couple days so you'll have a place to dive in.
