ConfigState is to indicate the deployment state of a storage item
(e.g., LUN) on storage device.
not-applied - the storage item is not deployed yet.
applying - the configuration of storage item is applying.
applied - the storage item is deployed successfully.
apply-failed - the storage item deployment is failed.
orphaned - the service profile is associated, but the deployed LUN cannot
find its LUN item in storage profile (either the LUN item is deleted
or the binding between service profile and storage profile is deleted).
not-in-use - the service profile is not associated with physical server
and the deployed LUN is currently not used by any initiator.
