ABDM M3

[khavinshankar]

This PR implements ABDM Milestone 3, fetching patient records from other HIPs.

Prerequisites:

1. The Health Facility ID should be configured for the respective facility.
2. Abha number of the patient should be linked (M1).
3. The care context of the respective consultation should be linked (M2).

The flow is as follows:

1. A consent request is created for the respective patient which is also stored in care before sending it to ABDM.
2. [Not Related to CARE] ABDM sends a consent request to the respective patient on their ABHA app.
3. ABDM sends the response from the patient (approved / rejected).

• If the patient approves, ABDM sends the respective consent artefacts (can be more than 1 i.e., 1 consent artefact is created for each HIP patient visited during the date range we requested in the consent request).
• If the patient rejects, only the rejection status is sent.

4. [Not Related to CARE in M3 context] Simultaneously, ABDM sends out the respective consent artefact to the HIPs.
5. Once we receive the consent artefacts, we store them and send a health information request to ABDM with encryption details (public key and nonce) + data push URL where the HIP can directly send the data.
6. [Not Related to CARE in M3 context] ABDM sends the data push URL and encryption details to HIP where the HIP encrypts the respective data (data will either be a raw file or in FHIR format) and send it directly to HIU through data push url.
7. Once we receive the data, we update the consent artefact status and decrypt the data and dump it to an S3 bucket using the already existing File Upload utility.
8. When the data is requested from the frontend, we fetch the data from the S3 bucket and send it.
9. If the patient revokes the consent or if the consent expires, we mark the file as archived with the respective reasons (expired or revoked) and after that the data is inaccessible by the frontend.
