[nbouron]

• Breaking change? (if so, please describe the impact and migration path for existing application instances)

What changes did you make? (Give an overview)

In some cases we need to set the loadBalancerIP with a preprovisioned IP in case of a service of type LoadBalancer, this is why i created this PR.

Is there anything you'd like reviewers to focus on?
