The new server implementation in Python implements request validation
using the Marshamallow package. With that, some requests are validated
directly by the marshmallow validator and do not return custom error
codes. Drop those error codes and other unused ones. Review the README
docs accordingly.
- Preserve the SQLite database and use SQLAlchemy to wrap db
interactions.
- Use Alembic for database migrations.
- Organize all the python modules on the new server/ directory.
- Use pytest for unit tests and organize test modules at server/tests/.
