[PRQ#45501] Deletion Request for metis4

MarsSeed [1] filed a deletion request for metis4 [2]: This legacy version from 2016 was only used by the several-years broken salome modules from same year. Its source cannot be downloaded (host unreachable). But it's safe to delete: the broken salome modules are also pending deletion, and the current version of Salome needs newer versions of its dependencies.
