[P1BIGROCKS-1360] Improve metrics collection and dashboards
[P1BIGROCKS-1360](https://jira.il2.dso.mil/browse/P1BIGROCKS-1360)
Most packages BigBang deploys today include robust `/metrics` endpoints but are not viewable in Grafana by default. This epic is to address missing dashboards for existing packages.
Each package should have
- [ ] Prometheus exporter for application specific metrics
- [ ] Grafana dashboards demonstrating how an SRE would monitor the application
- [ ] Uptime - when the application is not up/healthy it should be alerting
- [ ] Saturated - when the application needs to scale
- [ ] Horizontal Pod Autoscalers where appropriate - Package components that can scale horizontally should be configured to do so. Use Prometheus metrics if necessary.
