Update Orchestration Service so it can use the eCR Viewers save-metadata Endpoint

[JNygaard-Skylight]

What needs to be done

Add the eCR Viewer's new save-metadata endpoint to the Orchestration service, so that it can be used as a workflow step.

Why it needs to be done

Once this has been implemented we can remove the manual SQL calls in the seed-data script to insert metadata, and use just the Orchestration service (#2368). In addition this will enable the ability to pass the output of the message-parse to the save-metadata endpoint (#2368).

Acceptance Criteria

• Update /api/save-fhir-data in Orchestration service to handle the optional metadata paramter
• As part of a Orchestration config you should be able to save an eCRs metadata.
