Epic Goal

HyperShift provisions OpenShift clusters with externally managed control-planes. It follows a slightly different process for provisioning clusters. For example, HyperShift uses cluster API as a backend and moves all the machine management bits to the management cluster.  

Why is this important?

showing machine management/cluster auto-scaling tabs in the console is likely to confuse users and cause unnecessary side effects. 

Definition of Done

• MachineConfig and MachineConfigPool should not be present, they should be either removed or hidden when the cluster is spawned using HyperShift. 
• Cluster Settings show say the control plane is externally managed and be read-only.
• Cluster Settings -> Configuration resources should be read-only, maybe hide the tab
• Some resources should go in an allowlist. Most will be hidden
• Review getting started steps

Setup / Testing

It's based on the SERVER_FLAG controlPlaneTopology being set to External is really the driving factor here; this can be done in one of two ways:

• Locally via a Bridge Variable, export BRIDGE_CONTROL_PLANE_TOPOLOGY_MODE="External"
• Locally / OnCluster via modifying the window.SERVER_FLAGS.controlPlaneTopology to External in the dev tools

To test work related to cluster upgrade process, use a 4.10.3 cluster set on the candidate-4.10 upgrade channel using 4.11 frontend code.
