initial pass at arch diagrams both abstract and implementation

[CJ-Wright]

The idea is to capture all the moving pieces at both in an abstract, service oriented way and from an implementation perspective.

It might be helpful to add numbered labels to arrows- e.g

staged_recipes >> Edge(label="1. build") >> cis 

This ofcourse has a downside in that it implies a certain directionality.

Overall I think the numbered arrows might be useful.
