Switch to TypeORM's DataSource API (#299)

- Switch to TypeORM's DataSource API, rather than using the now deprecated ormconfig.json
- This will fix stage deployment not knowing how to deploy the database migrations

#297

> **NOTE:** This change requires the deployment scripts to be updated, please update them on the server before merging
