Do we need metrics to be (semi-)public?

Metrics for monitoring are currently only available on the machine, so you need to SSH there and forward the port to view anything. We could make this (semi-)public by forwarding through Caddy (on a subdomain?). Grafana supports OAuth via GitHub, so we could then set up login via a team.

I think it would be OK to make these more public, but limiting it to github login is probably the correct prudent choice given that the internet is a generically hostile place.

So this was primarily motivated by my laziness in not wanting to have to SSH to a machine and then set up a port forward. However, I think getting a reasonable naming scheme (#14) would go a long way towards this, and then I don't necessarily need public Grafana. Probably depends on how much work this ends up being.
