k8s: write out the defaulted fields so apply reports InfluxDB unchanged

The NetworkPolicy port gets protocol: TCP, the StatefulSet's volume
claim template apiVersion, kind and volumeMode: Filesystem. Kubernetes
filled these in itself, so every apply -k sent a patch and printed
"configured" although kubectl diff was empty. Validated offline.
