Asserts whether the target storage supports storing cloudinit images,
i.e. VM images, before creating a cloudinit image on the target storage.
Without the check in place, a cloudinit image can be created on the
storage, which does not support VM images, but won't be able to start
since any attached volume must be stored on a supported storage.
