Clean up Prometheus docs
The Prometheus docs are scattered in various places and when I tried to understand things, my brain hurt.
The main 3 categories are:
- How to set up Prometheus itself
- How to enable the Prometheus integration service
- How to make Prometheus gather metrics (and what metrics are supported)
Things are getting interesting when Kubernetes comes into place and the complexity of setting up things sky rockets.
I think the first thing we need to do is restructure some stuff, mostly under project/integrations/prometheus/
.
