Add zpool properties for allocation class space

Browse Source 
The existing zpool properties accounting pool space (size, allocated,
fragmentation, expandsize, free, capacity) are based on the normal
metaslab class or are cumulative properties of several classes combined.

Add properties reporting the space accounting metrics for each metaslab
class individually.

Also introduce pool-wide AVAIL, USABLE, and USED properties reporting
values corresponding to FREE, SIZE, and ALLOC deflated for raidz.

Update ZTS to recognize the new properties and validate reported values.

While in zpool_get_parsable.cfg, add "fragmentation" to the list of
parsable properties.
