Create a new production webapp using the frozen index on the staging ES
In order to test the swh-search behavior with real data, a webapp will be created and configured to use the production data and the cold swh-search index hosted on the staging ES node.
It's a cold index not updated since some time, but it a first step until a production ES cluster with live data is installed and backfilled with real data
