- Instantiate only one swh-worker@lister service
- Associate the lister's configuration for it to discuss with the right db (swh-lister on belvedere)
- Drops the lister_<techno>.pp manifests
- Removes each lister's configuration
- Configure the rocquenquourt nodes to deploy swh-worker@lister
This does not do any cleanups. This will have to be done later as extra
manual steps (after the puppet agent --test step).
