[libvirt] [PATCH 01/10] storage: Introduce internal pool support



To allow using the storage driver APIs to do operation on generic domain
disks we will need to introduce internal storage pools that will give is
a base to support this stuff even on files that weren't originally
defined as a part of the pool.

This patch introduces the 'internal' flag for a storage pool that will
prevent it from being listed along with the user defined storage pools.
