We need to specify 'low_water_mark' when creating a thin pool. Otherwise
a thin pool is created with 0 as low_water_mark and it will never
trigger a dm event so that an userspace daemon can do the resizing of
pool.

I am looking at how to pass this low water mark data to dm create. So
please do not merge this patch till we have capability to mention
low_water_mark argument for thin pool creation.
