Draft: Resolve "Get and show Prometheus container metrics"

Closes #743 (closed) #742 (closed) #712 (closed) #711 (closed)

This MR adds many dashboards that show a lot of data about our cluster, pods and containers.

Closes:

• #743 (closed) -- I changed this to check the helm-operator logs. I don't think we specifically had to test if eventrouter logs were there, just knowing that Loki works and that Grafana can show the data should be sufficient for this integration test
• #742 (closed) -- Obviously
• #712 (closed) Adds several dashboards with Kubernetes metrics
• #711 (closed) Adds less shitty nodes dashboard
