* Add lsm.Client.pool_raid_info() support:
* Use command 'storcli /c0/d0 show all J'.
* Use 'DG Drive LIST' section of output for disk_ids.
* Use 'TOPOLOGY' section of output for raid_type.
Since the command used here is not sharing the same data layout with
command "storcli /c0/v0 show all J" which is used by 'volume_raid_info()'
method, we now have two set of codes for detecting RAID type.
* Set lsm.Capabilities.POOL_RAID_INFO.
