devmapper: use proper DM_UDEV_DISABLE_*_FLAG when creating the thin-pool

Otherwise udev can unecessarily execute various rules (and issue
scanning IO, etc) against the thin-pool -- which can never be a
top-level device.

devmapper: Add option for specifying an lvm2 created thin-pool device

Ideally lvm2 would be used to create/manage the thin-pool volume that is
then handed to docker to exclusively create/manage the thin and thin
snapshot volumes needed for it's containers.  Managing the thin-pool
outside of docker makes for the most feature-rich method of having
docker utilize device mapper thin provisioning as the backing storage
for docker's containers.  lvm2-based thin-pool management feature
highlights include: automatic or interactive thin-pool resize support,
dynamically change thin-pool features, automatic thinp metadata checking
when lvm2 activates the thin-pool, etc.

Docker will not activate/deactivate the specified thin-pool device but
it will exclusively manage/create thin and thin snapshot volumes in it.

Docker will not take ownership of the specified thin-pool device unless
it has 0 data blocks used and a transaction id of 0.  This should help
guard against using a thin-pool that is already in use.

Also fix typos in setupBaseImage() relative to the thin volume type of
the base image.
