Revert Auto-Devops to auto_deploy_image v0.3.0

What does this MR do?

Helm cannot be upgraded to v2.16.0 because there's a problem with JupyterHub and we don't want to introduce more regressions.#35801 (comment 242561024)

Helm also cannot be downgraded for managed apps because the installed tiller complains about being newer.

So here we are only reverting Auto-DevOps auto-deploy-image for #35801 (closed) where we use tillerless helm.
