Goal

We should support deployment and upgrade of multi-arch clusters with heterogeneous workers.
It requires:

heterogeneous golden images support
instance type to let the VM owner require an arch for the VM
....

User Stories

As a VM owner, I want to run a VM running ARM RHEL on an ARM worker, regardless of the architecture that run my cluster's control plane.
- currently, when pointing to a ContainerDisk image URI, I cannot specify which architecture is being imported.
As a cluster admin, I want my DataSources to pull up-to-date images of all architectures supported in my cluster.

Non-Requirements

List of things not included in this epic, to alleviate any doubt raised during the grooming process.
