Since a future patch will start displaying thin logical volumes for a
logical volume group thin-pool, add the ability to display at the name of
the thin-pool name. This is done by adding 'pool_lv' to the list of
regex's and then when a "thin" lv is found, storing that pool name.
The result will end up being the following for a vol-dumpxml:
<source>
<name>thinpool_test_thin</name>
</source>
instead of an empty <source> </source> pair.
