How to set up and validate locally

1. Follow these instructions to setup Product Analytics in GDK.
2. Onboard a project at Project -> Analyze -> Analytics dashboards
3. View a dashboard, and verify the panel empty state is in the updated style
4. Now cause some panels to fail to load

• An easy way to do this is to temporarily modify a built in visualization, e.g. ee/lib/gitlab/analytics/product_analytics/visualizations/sessions_over_time.yaml and change the measure to some invalid value, so the query will fail.

1. Verify the new error state is shown, and the panel has a popover including a link to the troubleshooting docs
