In effect, this stops deploying swh-worker@archiver service on node with role
It was still running on uffizi node (and trying to connect to the now removed
swh-archiver db). It most probably is still running on other
storage*.euwest.azure nodes (I did not check yet).
Annex: This also removes the objstorage-checker which were never deployed (code
that is still living in the now archived swh-archiver repository).
