This is a rough first-draft change, with multiple flaws, intended to just start discussion around the feature request. Issues include: * It breaks compatibility, replacing the previous JSON /metrics * It crudely hand-generates Prometheus-formatted data * It would probably be better if it used https://pypi.org/project/prometheus-client/ But it works locally and I have some nice graphs!
