[New: openFATE 324968] clean old packages only after the whole repository has been re-built.

Feature added by: Ludwig Nussel (lnussel) Feature #324968, revision 1 Title: clean old packages only after the whole repository has been re-built. Buildservice: New Priority Requester: Desirable Requested by: Ludwig Nussel (lnussel) Partner organization: openSUSE.org Description: following up on https://bugzilla.suse.com/show_bug.cgi?id=482392 When a shared library package changes the soname, the resulting old binary rpms are immediately cleaned up after the new build finishes. This breaks bootstrapping if it hits eg rpm. Proposed solution would be to keep around old packages until the whole project is rebuilt -- openSUSE Feature: https://features.opensuse.org/324968
