sslip.io is hosted on GCP, not GKE

I don't need this k8s configuration for sslip.io (DNS, NTP) because I'm
no longer hosting on GKE now that it has an ephemeral IP instead of a
reserved IP because otherwise I'd have to pay $360 extra per year for a
premium-tier load balancer.

-Update GCP/GKE with the new executable:
+Check that the versions of the sslip.io DNS servers are the same:
 ```bash
-kubectl rollout restart deployment/sslip.io
-kubectl rollout restart deployment/sslip.io-nginx
