Adds the Result Feedback Service#81

- Once the task has been submitted, the user can submit feedback if the result seems correct - The service uses message queue to save the feedback to mysql db ToDo: - Currently the service just saves a piece of input image to db, which is useless. Save the images to a filesystem and save their paths to database instead. - Along with images, and feedback, store additional data like username, output of the model. - Add a check that only user who submitted the task can submit the feedback. - ~~Currently the code just adds a row to the table. If there is duplicate submission, overwride the result.~~ - ~~Update the architecture diagram and demo of Readme~~ - ~~Update CI files~~ - Add healthchecks for docker-compose (#26 ) References #36
