Aggregate logs so they are easily navigated

[d3adb5]

We should collect and store logs for all applications on the server so they are easy to navigate. Log aggregators like Promtail and log storage solutions like Grafana Loki are available for this.

This will make it easier to detect any problems by looking at logs for applications that may or may not still be around. There is a limit to how many lines of logs Kubernetes keeps around by default.
