Aggregate views (7542, 7622)

This fixes [#7542](https://issues.dp.la/issues/7542) and [#7622](https://issues.dp.la/issues/7622).  It syncs the QA app with the new global reports in the ingestion code.  It also dynamically calculates CouchDB view counts.  

See [#7542](https://issues.dp.la/issues/7542), notes 19-22.
Tie this to `~> 1.1.6` to match the gemspec?

I'd like to simplify the dependencies between Gemfile and gemspec, but it's out of scope for this PR.
