What is nodeRefclockActiveCGUSlotId?

This reports the physical slot ID of the card currently acting as the master Clock Generation Unit for the switch's timing system. On a switch with redundant CGU cards, an admin checks nodeRefclockActiveCGUSlotId to confirm which physical card is currently providing master timing, especially after a suspected CGU failover.
