ISPN-4991 Implement clustered cache statistics

Master only. Tristan should review
Sorry didn't notice this before, but is there a reason we have a priority here?  I really prefer if possible not to put ordering of the start components if not needed.  At a minimum we should comment why it has a priority since this means it usually has to start before/after another component (when someone else looks it would be very helpful for them to know why)
