Introduce `StatisticsAggregator` that handles aggregating statistics from multiple sources, and is well documented and tested 3. Rewrite existing statistics aggregation to use the new aggregator Note that this code is based on some authored by @crepererum for InfluxDB IOx. ## Are these changes tested? Yes, substantial new test coverage is added ## Are there any user-facing changes? No user facing change intended -- This is an automated message from the Apache Git Service.
