	gets a cached Monitor per name or will return none if it doesn't exist
static void	checkAll (bool checkAllSecondaries)
	checks all sets for current master and new secondaries usually only called from a BackgroundJob
static void	setConfigChangeHook (ConfigChangeHook hook)
	this is called whenever the config of any repclia set changes currently only 1 globally asserts if one already exists ownership passes to ReplicaSetMonitor and the hook will actually never be deleted
