Storing persistentId using an HTTP DataConnector

They can have side effects, and I have some that do, but there is certainly no inherent support for linking any of that stuff together, persistentIds don't know anything about that data connector.

Obviously one could run as a dependency, do something, and then populate a data store that would be read later by the stored ID connector.
