[Libvirt-cim] [PATCH] Add disk device='lun' support

[Xu Wang]

Besides 'disk', 'cdrom', 'floppy' and 'filesystem', there is one
more value 'lun' should be supported by value of device field in
the disk device. So this patch adds it into libvirt-cim. Now device
like <disk type='block' device='lun'> could be operated by class.
