* Using SNIA SMI-S 1.4 'Disk Sparing' profile to set Disk.STATUS_SPARE_DISK.
# Works well on EMC VMAX, Fujitsu ETERNUS, LSI MegaRAID.
# They are only array have spare disks I got access.
* Use vendor specific way to set Disk.STATUS_FREE:
1. EMC:
'EMCInUse' property of CIM_DiskDrive. False == Free.
# Tested on EMC VNX.
2. LSI MegaRAID:
StoragePool_InstanceID of CIM_StorageExtent,
if not contain 'Pool' keyword, it could be free disk or spare disk.
Then filter out spare disk, we got free disks.
# Tested on LSI MegaRAID.
Changes in V4(No changes in V2, V3):
* Remove LSI MegaRAID free disk code as we have dedicated plugin for
MegaRAID.
