Epic Goal

• Support OpenShift and the IPI workflow on GCP to use Confidential Compute service from Google Cloud
• Allow customers to scale their OCP clusters running on GCP with new confidential compute VMs.

Why is this important?

• Google Cloud customers want to leverage confidential compute service while deploying OpenShift on GCP

Scenarios

1. As a user, I want to be able to instruct the OpenShift Installer to use confidential VMs while deploying the platform on Google Cloud so I can use the confidentail compute service from GCP on every Node.
