Distribute Hosted Cluster workloads

HyperShift enables implementing the strategy to colocate and isolate pods for Hosted Clusters. As a management cluster operator you can leverage the following Node labels and taints:

hypershift.openshift.io/control-plane: true

hypershift.openshift.io/cluster: ${HostedControlPlane Namespace}

• Pods for a Hosted Cluster tolerate taints for control-plane and cluster.
• Pods for a Hosted Cluster prefer to be scheduled into the same Node.
• Pods for a Hosted Cluster prefer to be scheduled into control-plane Nodes.
• Pods for a Hosted Cluster prefer to be scheduled into their own cluster Nodes.

If the ControllerAvailabilityPolicy is HighlyAvailable Pods for each Deployment within a Hosted Cluster will require to be scheduled across different failure domains by setting topology.kubernetes.io/zone as the topology key.
