Clean misplaced ERROR/WARNING messages triggered by the queue cleanup runner

As noted by @jleduc in the issue https://gitlab.cern.ch/cta/operations/-/issues/937#note_6265136, the new queue cleanup runner (added on release 4.8.0 and executed on the maintenance process) is issuing a large number of WARNING messages.

These messages are most probably harmless and do not imply that the object store is performing badly. Therefore, they should be re-evaluated and, if justifiable, have their priority reduced or be removed.
