New feature: Dashboard override granularity

[gbrian]

Hi there,

I'd like to start implementing granularity override.

My notes

Like in Grafana (http://grafana.org/) I'd like to have a time period control for the dashboard.
It will allow users to select the period (granularity) to visualize.

Todo:

• server: Allow dashboard/id/ to receive optional parameters: since, until
• server/client: Add granularity property to dashboard: {"granularity":{"since":"now-1d","until":"now"}}
• client: Change slice.querystring to read granularity and send to the slice endpoint
  extra bonus:
• client: Add granularity-picker to dashboard (https://github.com/grafana/grafana/tree/master/public/app/features/dashboard/timepicker)
  • Modify granularity-picker to allow "Default" that means the granularity setup on each slide
• Add new property to dashboard definition: granularity that will override slice ones.

Comments? Thanks
