This pulls the prometheus monitoring stack into the web UI allowing any future React-like Javascript application to have a self-contained way for basic monitoring data. The vision is this will power visualizations in the admin dashboard. For simplicity of review, the changes to go.mod/go.sum will come in a follow-up commit.
