We only want to scope (i.e. prefix with hostID) those addresses that are deemed loopback, to disambiguate them. Otherwise, we want to leave addresses in unscoped form, so they can be matched, and links between communicating nodes properly made. So, we make the isLoopback check in MakeAddressID, and omit hostID if the address isn't loopback. So far so good. But this breaks topology rendering, as we were relying on extracting hostID from adjacency node IDs, to populate origin hosts in the rendered node output. So we need another way to get origin host from an arbitrary node. A survey revealed no reliable way to get that information from IDs in their new form. However, we have access to node metadata, so this changeset introduces the OriginHostTagger, which tags each node with its origin host, via the foreign-key semantics we'll use going forward.
