Insights: Served cached insight data against insight dashboards

Created by: umpox

We might be able to cache the result of code insights to greatly improve performance when switching between dashboards

1. Go to https://k8s.sgdev.org/insights/dashboards/frontendPlatform
2. Using the dashboard selector, navigate to a different dashboard
3. Navigate back to the frontend platform dashboard using the selector
4. Notice how we have to refetch data to display insights

Are we able to leverage the Apollo cache here to improve performance?
