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.
We could make a separate ticket to add a rake tasks for this.  It could stop delayed_job, clear out the job queue table, clear the files from disk, and restart delayed_job, or something like that.  This particular function was certainly this way before; it's not an issue with the current revision.
