What this PR does

In this PR I'm upstreaming a change we've rolled out at Grafana Labs: use fully qualified K8S domain names to reduce DNS lookups made by Mimir.
This adds a final . to DNS names, so they are not looked up via the DNS search path which usually has 5 entries in Kubernetes.

Which issue(s) this PR fixes or relates to

N/A

Checklist

  • Tests updated
