Epic Goal

Allow multiple agents to co-exist

Why is this important?

Between MCE and ROSA-HCP, there is becoming a high probability of having multiple agents attached to the same cluster. We need to this to work and NOT cause a collision that causes the cluster to be offline from management

Scenarios

1. I want to import a ROSA-HCP cluster into ACM
2. I want to install MCE on a ManagedCluster so I can provision Hosted Control Planes
3. I want to import an MCE into an ACM

Acceptance Criteria

1. A managedCluster with MCE can be managed by an ACM
2. A ROSA-HCP cluster can be managed by an ACM

Dependencies (internal and external)

1. ROSA-HCP OCM-2135 is complete
2. ACM agents start to deploy in the non-standard namespace by default

Previous Work (Optional):

1. The ability to deploy the ACM agent and Addons to a user defined namespace(s)

Open questions:

1. Should we change the default namespace from open-cluster-management-agent and open-clsuter-management-agent-addons to <ACM_CLUSTER_NAME>-agent and <ACM_CLUSTER_NAME>-agent-addons
2. Should we automatically import MCE clusters into ACM (THIS IS OUT OF SCOPE TO COMPLETE IN THIS EPIC, but we should decide whether we want to do this)
