This simply tracks the instance-used spindles (using hard-coded '1' per instance), and additionally prevents additions in soft-mode when we go over the limit. Note: there's an assymetry between addSec and removeSec (basically secondaries should only exist with DTDrbd8, so the check for uses_disk is superflous), will be cleaned up later.
