Goal
Define the cluster creation experience for HAC Infra (OCM) to provision a ROSA HyperShift hosted cluster.

Background
HyperShift is a deployment model that provides OpenShift clusters where the control-planes are externally managed on another cluster (that we call the "Hosting Service Cluster") as pods.

Personas to focus on

• Cluster Service Provider - the user hosting cluster control planes, responsible for up-time. UI for fleet wide alerts, configuring AWS account to host control planes in, user provisioned infra (host awareness of available compute), where to pull VMs from has cluster admin management
• Cluster Service Consumer - the user empowered to request control planes, request workers, and drive upgrades or modify externalized configuration. Likely not empowered to manage or access cloud creds or infrastructure encryption keys.

Terminology

• Hosting Service Cluster - An OpenShift cluster which hosts HyperShift and zero to many Hosted Clusters.
• Hosted Cluster - An OpenShift API endpoint managed by HyperShift.

Requirements

• Identify the ideal user experience to provision a ROSA HyperShift hosted cluster (leveraging the ROSA cluster creation wizard)

Deliverables

• High level workflows
• Mock ups to support the identified workflows
