Add log aggregation

[hackartisan]

Acceptance Criteria

• There's a place to go to look at all logs for DPUL Collections in staging.
• The logs are searchable.
• it's documented in the readme

First Step

Look at https://dev.to/justinepdevasia/docker-log-observability-analyzing-container-logs-in-hashicorp-nomad-with-vector-loki-and-grafana-4dp4

So we can't pay for Datadog for our staging boxes, so I think log aggregation here probably means implementing those little experiments I did around Grafana & Loki, like in https://dev.to/justinepdevasia/docker-log-observability-analyzing-container-logs-in-hashicorp-nomad-with-vector-loki-and-grafana-4dp4.

Otherwise we could probably add a console command to tail logs...maybe even all of them somehow.

https://github.com/tolitius/entail is a utility that would let us tail all logs for a job
