Background

To enable a quick start in CAPI, we want to allow the users to provide just the Machines/MachineSets and the relevant configuration for the Machines. The cluster infrastructure is either not required to be populated, or something they should not care about.

To enable the quick start, we should create and where applicable, populate required fields for the infrastructure cluster.

This will go alongside a generated Cluster object and should mean that the `openshift-cluster-api` Cluster is now infrastructure ready.

Steps

• Create a separate go module in cluster-api-provider-vsphere/openshift
• Create a controller in the above module Go to manage the VSphereCluster resource for non-capi bootstrapped clusters
• Ensure the VSphereCluster controller is only enabled for VSphere platform clusters
• Create an "externally-managed" VSphereCluster resource and manage the status to ensure Machine's can correctly be created
• Populate any required spec/status fields in the VSphereCluster spec using the controller
• (Refer to openstack implementation)
•
