Export dashboard for external use via HTTP API

Hi again,

Oh, I see. I believe I never saw that format before, thank you! On this matter, I should have followed your original references.

While I have nothing significant to contribute now, I still want to reference the corresponding place in the code base, where this JSON representation is generated. It is DashboardExporter.ts.

Also, I created a note at Add converter for dashboard JSON in "export format" representation · Issue #8 · panodata/grafana-client · GitHub about this. I will be happy to hear your opinions about it.

With kind regards,
Andreas.
