Value Statement

As a cluster Operator, I want to import a cluster to be managed by RHACM hub cluster.

Once cluster is imported, I want to be able to : add nodes using the ClusterInstane yaml and gitops, then will be able to remove it or add and remove more nodes.

There are scenario when a cluster or a few clusters are installed before adopting hub cluster and once hub cluster is ready, I want to be able to import those clusters as per above.

Requirements: 

• importing a cluster using ClusterInstance Manifest. 
• Scaling up (Adding a node ) using ClusterInstance Manifest. 
• Scaling down (removing a node) using ClusterInstance Manifest. 
• Applying Policies
• upgrading imported cluster to ensure that all ACM use cases properly work on an imported cluster
• Writing QE Functional test cases for this feature if need be.

Ensure the issue title clearly reflects the value of this user story to the
intended persona. (Explain the "WHY")

Definition of Done for Engineering Story Owner (Checklist)

• importing a cluster using ClusterInstance Manifest. This is done : [ ACM-24929]
