* Add lsm.Client.pool_raid_info() support:
* Treat NetApp ONTAP aggregate as disk RAID group.
Use na_disk['aggregate'] property to determine disk ownership.
* Treat NetApp ONTAP volume as sub-pool.
Use na_vol['containing-aggregate'] property to determine sub-pool
ownership.
* Set lsm.Capabilities.POOL_RAID_INFO.
