Matt McNaughton 0a56b9db51 Add description of k8s dns to guestbook (#5201)
Going through the guestbook tutorial for the first time,
the deployment configuration mentioned that whether my configuration
included a DNS service would dictate which env value I used for the
`GET_HOSTS_FROM` variable. According to
https://kubernetes.io/docs/concepts/services-networking/dns-pod-service/,
k8s includes DNS by default starting with v1.3.

Add this additional info to help the user better understand when DNS
may/may not be enabled.
