User Story:

As a developer, I want to be able to:

• Pass an ingressAddress resource through a manifest to be consumed by the ingress controller.

so that I can achieve

• Using pre-existing compute_address for the ingress controller
• to enable creating GCP clusters with Shared VPC networks using the IPI workflow.

Acceptance Criteria:

Description of criteria:

• A field is added to the appropriate manifest(s) to accept a pre-existing compute_address
• this field is used by the ingress controller when deploying the ingress load balancer

(optional) Out of Scope:

Adding functionality to the installer to pass this field into the manifest is part of another card.
