    Allow disk driver to be chosen per image
    
    This allows for an image in glance to be annotated with a
    property describing the required disk / cdrom bus type.
    
    eg
    
      # glance image-update \
               --property disk_bus=ide \
               --property cdrom_bus=ide \
               f16-x86_64-openstack-sda
    
    Valid bus values vary per the libvirt_type setting:
    
     qemu/kvm: 'virtio', 'scsi', 'ide', 'usb'
     xen: 'xen', 'ide'
     uml: 'uml'
    
    Requesting an unsupported disk bus will cause the guest
    instance to fail to launch.
