Enable new echarts metrics dashboard by default
Currently our echarts based dashboard is behind a Feature Flag. We plan to have feature parity with the existing dashboard during %11.8.
Since we should have feature parity, we should remove the feature flag that is currently gating the new echarts based dashboard. This would enable it globally for everyone, and we can remove the old code.
Issue is considered complete when:
- Removed the feature flag
- Old charts code is removed
