Support grafonnet autocompletion

[v-zhuravlev]

Hello!
We now have autocomplete feature, unfortunately it doesn't work for generated grafonnet lib:
https://github.com/grafana/grafonnet

Is there a way to add it?

This library is very important for designing clean Grafana dashboards as-code. And such autocompletion can add dramatic speed boost to this process, getting near to composing dashboards in Grafana UI.

hmm that's tricky. Grafonnet is generated on the fly from jsonschema. To do autocomplete, we'd have to do the same in the language server and it can be a quite expensive thing to do. The language server avoids evaluation at all costs in order to provider sub-second suggestions

Is this something that can be put behind feature opt-in flag?

[v-zhuravlev]

We plan to create Grafana cloud integrations using only that lib as base, so this feature can be game changer.

I've recently learned about LSIF, a format that can store data about an LSP workspace. It would be a bit of a stretch but perhaps we can generate such a file for Grafonnet and tell the language server about it somehow.

Grafonnet is now statically generated, this means it can be used with the language server.
