Additional info for leveraging this in kubernetes

[woodmicha]

FIrst, I really appreciate you putting this repo together! I had some challenges getting the metrics from this container into my k8s based prometheus. I could curl the service and it was working fine but not showing up in prometheus.

After much searching found out you have to annotate your deployments for prometheus to discover them. I'm pasting my simple example below in hopes you can include this type of info in your README.md Perhaps this is common knowledge but my sense is this would help noobs like me get working faster.
