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.
Remove this. As discussed in channel, it breaks on threaded servers (and doesn't seem to be called from the controller).

If you need it required here, remove `require 'zip'` throughout and try adding to Contentqa::Engine; if that doesn't work, we'll need to use a Railtie.

Later we should move all dependencies in this and `v1` to an initializer in a Railtie.
