As an Alibaba Cloud customer, I want to create an OpenShift cluster with the Assisted Installer using the agnostic platform (platform=none) for connected deployments.

Epic Goal

• Start with the original Alibaba Cloud Red Hat OpenShift Container Platform 4.6 Deployment Guide and adjust it to use the Assisted Installer with platform=none.
• Document the steps for a successful installation using that method and feed the docs team with that information.
• Narrow down the scope to the minimum viable to achieve Tech Preview in 4.16. We'll handle platform=external and better tools and automation in future releases.
• Engage with the Assisted Installer team and the Solutions Architect / PTAM of Alibaba for support.
• Provide frequent updates on work progress (at least weekly).
• Assist QE in testing.

Why is this important?

• In order to remove IPI/UPI support for Alibaba Cloud in OpenShift, we need to provide an alternate method for Alibaba Cloud customers to spin up an OpenShift cluster. To that end, we want customers to use Assisted Installer with platform=none (and in future releases platform=external) to bring up their OpenShift clusters.

Acceptance Criteria

• Reproducible, stable, and documented installation steps using the Assisted Installer with platform=none provided to the docs team and QE.
