Counting matching messages slows down queries /messages by several seconds because the messages table is too large. This PR mitigates the problem by adding a cache in front of DB queries in order to reduce the average load on CCNs while keeping exact message counts. The default cache TTL is 5 minutes but can be configured through the new perf.message_count_cache_ttl config value.
