Once we have CAPI as the backend for MAPI and CAPI machines, we have the ability to switch to using bootstrap data requests, via a minimal bootstrap provider.

The bootstrap provider could be responsible for creating a small ignition stub, pointing out to the MCS endpoint, but, adding some additional context such as per node bootstrap secrets or IPAM configuration.

We would like to understand:

• How would changing to per node bootstrap data be accomplished, what is the migration story?
• What are the benefits, and how would things like per node bootstrap credentials work today? Does this allow for a reduced reliance on cluster-machine-approver?
• Where do we have customers requesting per node configuration today? Potentially baremetal and other IPAM related cases
