Once every swh modules have been deployed, we should cleanup the tasks submodule's collaborator (lister/loader/indexer)'s no longer useful configuration.
Once again, one step closer to T1410, T826.
Also cleanup the remaining dangling debian/ tree arborescence in every module's master branch (debian packaging in swh modules starts in debian/unstable-swh branch now).
Most if not all of the debian packaging should have been fixed once T1525 is done.
Then package and redeploy.
