15b7f9d83f 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.
