Code Issues Proposed changes

Add share_type filter support to pool_list 

Administrators intend to get the pool's information filtered
by share type(actually filtered by share_type's *extra_spec*)
more directly.
The blueprint is to add a filter key 'share_type' to cover
this situation.

Implements: blueprint pool-list-by-share-type
