Comment 2 for bug 1788837

My bad i assumed the return code 1 was triggered by the warning, having a closer look at glance-manage.log showed errors :
trying to drop already non exitant column and index in ocata_contract01_drop_is_public.py
during Liberty to Queens upgrade using ceph backend

migration is now fine and return code is now 0 despite the warning

sorry for the noise
