satusehat: new adaptor to handle auth and expose http functions

[aleksa-krolls]

Background

SATUSEHAT is the Indonesian government's FHIR health information system. A customer wants to send FHIR-format data from CommCare to SATUSEHAT, so we need to create a new adaptor to support this project.

Request

Create a new satusehat adaptor that:

1. handles authentication
2. exposes all http functions so that we can send requests to the dozens of API endpoints the adaptor exposes (incl. /patient, /encounter, etc.)

To test

• Use this postman collection: https://www.postman.com/satusehat/workspace/satusehat-public/request/30206597-5a1e7e8e-8381-4854-953f-761a622cca86
• For the staging API credentials, see LP HIH ASRI SATUSEHAT creds for the organization id, client key, etc.
• Once auth is built in the adaptor, you can trying using the adaptor to send a GET request to this Organization endpoint (and use the organization id from the LP credential as the parameter /api/Organization/:id)

Staging login url: https://api-satusehat-stg.dto.kemkes.go.id/oauth2/v1/accesstoken?grant_type=client_credentials
