Although the delta implies that this is actually adding code, it's
better than it looks, because some of the stuff in ContactFlowUtils
is duplicating more generic methods in ResourceFlowUtils, which
can be deleted when the domain and host flows are cut over.

This allows us to inject an optional once, in FlowRunner, and
inject a non-null value in the flows (not done yet, after this
