When online_data_migrations raise exceptions, nova/cinder-manage catches the exceptions, prints fairly useless "something didn't work" messages, and moves on. Two issues: 1) The user(/admin) has no way to see what actually failed (exception detail is not logged) 2) The command returns exit status 0, as if all possible migrations have been completed successfully - this can cause failures to get missed, especially if automated This change adds logging of the exceptions, and introduces a new exit status of 2, which indicates that no updates took effect in the last batch attempt, but some are (still) failing, which requires intervention.
