Design for a kvm provider type: SSH-forwarded libvirt socket, multi-host
config with placement.zone selecting the host, bridged networking with
ARP/guest-agent IP discovery, operator-fetched distro cloud images cached
in the host's storage pool, and a NoCloud seed ISO carrying the CRD's
cloud-init user-data.
