feat: Add simple grafana dashboard that can be used when running sidecar (#1856)

Also includes minor tweaks to the compose file. The node is now pruned
more to keep the volume size small and maintainable.

cAdvisor, grafan, loki, and prometheus were also added to the docker
compose file so we can easily create a local grafana dashboard
