Integration Information Model revamp

Some examples of where we might have used PARTY datatypes

Look at section 7,8,9. Sections 7,9 we could probably handle with participations if we were able to add role to PARTY_IDENTIFIED + other_details.

In the lab archetypes we need a place to handle the lab details, lab contact details - names, places, people - hard to squeeze into participations or other RM attributes.

Again possibly feeder_audit or participations might work but we need yo be able to extend PARTY_PROXY with other_details and find a better way of making these visible and locally meaningful in the template. It is just really hard to explain these things to devs and clinicians alike.
