The long term goal here is to eventually create python-grafana from our embedded grafana.py file. So, most of this code just makes the Grafana object more user friendly. However, we've also added some validation around create_dashboard, we added some checks before we create and after. To ensure we actually created our new dashboards. Finally, add some sphinx docs since everybody loves documentation. Change-Id: Icbba403afe5208fbef1855118d4c3f4293461e00 Signed-off-by: Paul Belanger <pabelanger@redhat.com>
