Scenario - Support Kubeflow deployment with an ILB

The current ingress deploys a public load balancer and there should be a provision to deploy an internal load balancer if required.

Start by reviewing the current ingress deployment configuration and how AKS load balancers are selected. Confirm the desired internal load balancer option and its completion criteria with maintainers; done means deployments can choose an internal load balancer while existing public behavior remains available.
