Pacman: Message Parsing Service

[emmastephenson]

What needs to be done

Move message parsing functionality that's used by the eCR Viewer directly into the orchestration service.

Why it needs to be done

This will make our application stack significantly easier to maintain, and should also improve our networking performance for the Viewer.

Acceptance Criteria

• eCR Viewer pipeline doesn't call out to message parser to extract data - it's done directly in orchestration.

Technical Notes

Notes from planning epic:

• Extracting fields out of the FHIR bundle in a flattened way
• May not want to port over PHDC conversion pieces
• Less about moving over existing codebase, and more about extracting the data out directly. What gets returned to eCR Viewer as metadata
