Update intra-resource relationships to use createMappedRelationship

[ndowmon]

In Azure, entities can relate to other entities outside of their own subscription. For example, a virtual machine in subscription 1 could be launched from an image hosted in subscription 2. For most / all of the build*Relationships steps in this project, we simply try to find the target entity in the job state, and if it does not exist, we don't build the relationship.

Since these relationships can natively be built across azure subscriptions, we should either default to creating mapped relationships (and have some sort of resolution process before the synchronization step to resolve discrete relationships) OR to create mapped relationships when the target entity is not found in the job state.
