Make the source of the object counts configurable
The webapp retrieves the count of objects from storage : https://forge.softwareheritage.org/source/swh-web/browse/master/swh/web/common/archive.py$920-926
In order to progressively deploy in staging and production, it should be made configurable to get them from storage or swh-counters
