Setup S3 for local development

[BobanL]

What needs to be done

• Setup S3 localstack in docker-compose.yml
• Update create seed data to save to S3 bucket

Why it needs to be done

• Since all potential partners will be using some sort of blob storage to store the fhir bundles we should be able to mock that experience locally
• Developers need a local development environment to mock an S3 bucket

Acceptance Criteria

• [ ] S3 bucket is running when running npm run local-dev
• [ ] FHIR data gets saved to S3 bucket
• [ ] Environment variables values are documented and set to connect to S3 bucket
