Logging infrastructure Nomad files

[tpendragon]

I'm largely just testing these. It's a combination of https://atodorov.me/2021/07/09/logging-on-nomad-and-log-aggregation-with-loki/ and https://dev.to/justinepdevasia/docker-log-observability-analyzing-container-logs-in-hashicorp-nomad-with-vector-loki-and-grafana-4dp4.

Big gaps:

1. Grafana's weird, we'd have to get used to it.
   • Everyone said they like it better, so uh, not a problem.
2. Data persistence for Grafana/Loki
   • We decided on a host volume: [Nomad] Add host volumes for Loki + Grafana + Grafana Proxy princeton_ansible#5476
3. URL for Grafana
   • Requested grafana-nomad.lib.princeton.edu ([Domain Request] grafana-nomad.lib.princeton.edu princeton_ansible#5475)
4. Auth decision
   • They have Github OAuth! I'm gonna use that.
