This change implements a Centaur SCOM cache for sensitive SCOM registers. The
cache is initialized and enabled before the first Centaur SCOM, and disabled
just prior to locking down the Centaur configuration. Once the Centaur has been
locked down, the real register values are compared to the cache entries, and the
Centaur is deconfigured (not garded) on any mismatch in assumptions.
