resolve PerDestinationStoreLimitTest - have store size reflect stored messages rather than disk usage (so now it reports used rather than allocated disk soace excluding the index) such that 100MB messages gives store size ~100MB while disk utilisation may be bigger. getDiskSize still exsits to get totall allocated space on disk. This allows configured limits to be more accuratly enforced and fixes this test regression. Also calculation is accumulative rather than on demand so it much faster
