Add Infra metrics and dashboards

[puckpuck]

Feature Request

With Docker stats added to the demo in #1650, we need to ensure that we add the rest of the functionality to get infra metrics working and consumable for the user.

• Grafana dashboard with docker stats by service
• Equivalent metrics integration for Kubernetes / Helm deployment
• Grafana dashboard for kubelet stats by service
• Optimization of Prometheus deployment with increased metrics load
