state: adjust compare for catalog events 

Document that this comparison should roughly match MatchesKey

Only sort by overrideKey or service name, but not both
Add namespace to the sort.

The client side also builds a map of these based on the namespace/node/service key, so the only order
that really matters is the ordering of register/dereigster events.
