[FEATURE] V2 Resource support

[mukhtarkv]

Is your feature request related to a problem? Please describe.
Recently I see different default JSON export code for dashboards. I have to navigate to advanced options and select classic resource to be able to work with PromEx.

Describe the solution you would like to see
I would like to see example of Grafana Dashboard template code for V2 Resource. I am also interested in how you handle annotations where you handle folder related metadata.

How would you expect this feature to work
Updated API and eex template.

Additional context
Add any other context or screenshots about the feature request here.

Hey there! This is a pretty timely comment. I am currently working on a Jsonnet compiler in Elixir so that I can lean on https://github.com/grafana/grafonnet and build the dashboards dynamically with Grafana's very own chart/panel definitions.

The Jsonnet compiler is almost complete and then I'll look into incorporating that into this library along with Grafonnet!
