The query itself is too expensive to be run on large Wikimedia wikis. So
put it behind WAN cache and touch the check keys for each category
whenever those have errors added or deleted from them.
If this happens to get out of sync, it will get fully refreshed
regularly when the totals are sent to statsd.
WANObjectCache's 'lockTSE' feature will help avoid cache stampedes that
made this query expensive in the past.
