Create example workflow manager integration

It currently is possible to wrap the different pipeline components as discrete tasks in popular workflow managers. Enough refactoring work on the pipelines has happened that it shouldn't be a huge lift to create to create an example integration that builds on what's there.

The issue names no files, tests, or workflow manager. Start by locating the existing pipeline components and their task boundaries; done means an example integration that wraps those components as discrete tasks.
