lvm: Report used/free space for thin pools and thick snapshots

Thin pools and traditional snapshot volumes fill up as I/O is performed
to their associated thin volumes or origins.  When they run out of free
space, things break, so it's useful to monitor their disk utilization.

Add new plugin instances for thin pool data LVs, thin pool metadata LVs,
and thick snapshot LVs, each with "used" and "free" type instances.
