lsdasd: Add support for thin-provisioned volumes
Make lsdasd aware of thinly provisioned (Extent Space Efficient (ESE)) DASD volumes. The ESE information is added to the discipline output and the extended output additionally lists information about logical capacity, allocated space, and the extent size.
