LoadBalancer option for common service

I have a setup on Google Kubernetes Engine where I deploy a cluster in each of three regions. To index data, I need access from outside the cluster, but all I need is an internal IP. I am using annotations that GKE provides for this but it requires being able to set `spec.Type: LoadBalancer` for the service.

```yaml
apiVersion: v1
kind: Service
metadata:
annotations:
cloud.google.com/neg: '{"ingress":true}'
networking.gke.io/internal-load-balancer-allow-global-access: "true"
networking.gke.io/load-balancer-type: Internal
spec:
type: LoadBalancer
...
```

is there a way to set the type for the commonService

Locate the commonService generation path and inspect how its Service spec and annotations are currently exposed. Verify how a caller can request spec.type: LoadBalancer for the common service, then test that the resulting Service retains the GKE internal-load-balancer annotations and provides the requested internal access.
