This PR exposes some prometheus metrics on the /metrics endpoint. The metrics endpoint is only available to localhost so Grafana Alloy can scrape it and push to the cloud.
It also enables the Go prometheus client so we can monitor the Go app metrics.
Additional things that needed doing:
Update UFW rules to allow :8090 (and reload)
Update Grafana Alloy configuration to scrape localhost Go app metrics (and reload it)
