Workflow: Move model notification up to top-level

Simplifies the workflow by removing nested templates. I.e. instead of having
a template consisting of building-then-post-service, we add the building
and service-posting as top-level tasks in do-all, and add the builder as a
dependency of the service.

Needed beause of argoproj/argo-workflows#1713
