New /link API endpoint

[ericbuckley]

Summary

Create a new API endpoint, /link, that behaves similar to the existing /link-record endpoint. The difference is that it will accept a raw PII payload rather than a FHIR bundle.

Acceptance Criteria

• A new API endpoint /link that returns matches
• Renaming the person.internal_id column
• Adding the patient.reference_id column
• Test cases for the new API

Details / Tasks

Inputs

The new endpoint should accept the other parameters like external_person_id and algorithm, the new record parameter should map to the PIIRecord class. That is the PIIRecord class should act as a validator and serializer for the incoming data.

Outputs

The output will be different in that we will no longer return a FHIR bundle. Instead a payload should be returned with the following information.

• is_match: bool
• patient_reference_id: uuid
• person_reference_id: uuid

Model Changes

• rename person.internal_id to person.reference_id
• add patient.reference_id to the Patient table (uuid with a default value of uuid.uuid4())
