Revert "GKE: enable UDP services for DNS & NTP"

This reverts commit 9c888f390dd63ef18aaf34cacdd5128d30994e22.

I don't need UDP to pass through the nginx-ingress-controller; I can
create a LoadBalancer service to pass it directly to the sslip.io DNS
server, which preserves the source IP address, which is important for
logging & IP lookups via TXT records
