Tool/cli to check grafana dashboard json schema

#1

Dashboards can be provision using json http://docs.grafana.org/reference/dashboard/
with schemaVersion however I am missing tool (CLI would be best) to check any given dash.json for invalid schema / warnings.

This would could be very useful during testing and dev work ( similar likepromtool for prometheus syntax checks.

I welcome any feedback ( perhaps that schema lives in form of json-schema ?).
I am considering staring as standalone go cmd if that makes sense ( not missing anything )?
I image that could be later added to grafana-cli perhaps.

Came here with same thoughts. A JSON Schema for dashboard JSON is very much needed.
