This reverts change I98a75cbf119ba8126253a681c046f4cf44b1607e.
Volume backup tests create a container when Swift is used as a backup
driver. This causes a failure of an object storage test [1] as it
expects no containers being present before the testing.
This patch fixes the cleanup by deleting properly the containers
created during the volume backup tests. Before the deletion we check
using a new tempest.conf option whether swift is used as a backup
driver.
This patche also un-skips the
test_volume_backup_create_get_detailed_list_restore_delete test as the
patch ensures that we do not use the container parameter in the API
call when Swift is not used as a backup driver.
