Update container to Use Flask-RESTX

[tzuanwang]

As a developer I need to update the container to use Flask-RESTX So that the service can have a standardized API structure and easier integration of Swagger documentation

Details and Assumptions

• The microservice will be refactored to use Flask-RESTX
• Python modules are installed by poetry

• The refactoring will follow the file layout outlined in lab-flask-restplus-swagger

  Acceptance Criteria

  Given the microservice codebase and docker container rebuilt
  When I reopen the codebase in container
  Then the service should follow the Flask-RESTX file layout, ready for OpenAPI andswagger documentation development
  And the microservice should maintain the same functionality as before refactoring

JSON error messages are guaranteed by flask-restx. Most error handlers and jsonify should be removed after each route is decorated with flask-restx api.
