[migration] merge migration and its rollback into one testcase
Currently we are running rollback test as a child after its parent migration test done successfully. By this way, we have to divide the workflow into two tests (migration and rollback) and need to create after-migrated hdd image.
The desired goal is to do a migration and its rollback at one go without two parts and creating the image.
