Adds an additional optional flag (-rollback-only) to delete the current application and remove the venerable suffix from the venerable application instead of performing a deployment. Is assumes that the venerable application was not deleted after the last successful deployment (using -bstop or ignore). The use case is to run more sophisticated integration/end-to-end tests after a successful deployment and have the option to roll back to the previous version if some test case fails.
