Migrate uses the same mechanism in the backend than Resize and so the
steps and step names are similar. Currently when using the --wait
option with 'migrate', we wait forever because the status won't get to
active until the user performs an action. This makes it return on
verify_resize status just like 'resize' does, so that the user can
perform the next manual step.
