How to use Prometheus annotation

[Kyrremann]

I'm trying to communicate with the redis-exporter in each rfr- pod, but as the normal Prometheus annotations are missing, and I only have one service to communicate with all three of my pods, I don't get the data I want.

Have you thought about adding the annotation to each redis-exporter container? So that we can scrape each of them, instead of a service point?

The annotation I'm thinking about is:

  Annotations:  prometheus.io/path=/metrics
                prometheus.io/port=http
                prometheus.io/scrape=true

Also, do we really need the service point for Prometheus scraping? Isn't it better to scrape each pod with an redis-exporter, so we get more precise data about the load?

I'm writing the code needed for it for us. Can create a PR when I'm done.
