This has been covered by the new deploy component: https://github.com/kubeflow/pipelines/tree/master/components/gcp/ml_engine/deploy

The component outputs: a) the found gcs path to the model file; b) the full version resource name
It also display online prediction instructions in a markdown viewer which demonstrate the command line and oauth playground link to invoke online prediction.
