Add Nava metrics to sprint metrics board

[widal001]

Summary

Duplicate the following Metabase questions and add them to a Nava tab in the sprint metrics dashboard:

• Sprint burndown by issues
• Sprint burndown by points
• Sprint burnup by issues
• Sprint burnup by points

Or alternatively, find a way to update this model so that it uses a variable for the project number (i.e. 17 for Agile Six and 13 for Nava) and then use the same charts across both tabs of sprint metrics dashboard.

Acceptance criteria

• The sprint metrics dashboard has been updated to include both an Agile Six tab and a Nava tab
• Both tabs have the following metrics:
  • Last updated
  • Days left in sprint
  • Sprint burndown & burnup by issues
  • Sprint burndown & burnup by points
