Deploy exercise verifier as a Flask API

[Bernardstanislas]

The idea of this issue is to prepare the work of creating a web version of Starklings.

A first step for that would be to have a simple Flask backend that will expose one route POST /exercise/check?path={exercise_path} that returns the errors of the exercise file given as the request body.

This would be used by a frontend exposing a code editor to the user, and calling this API to get a correction on the exercise.

🗒️ Information about the data needed for front end : (types are for ref. it can be easily handled with JS if needed)

• user id (number or strg)
• user address (number)
• user progression ⚠️ by exercice type (Array of Object)

  [{
  "userProgression": {
  "syntax": {
    "syntax0": "success",
     "syntax1": "not-started"
   }
  }
  }]

• also a list of all exercices (type + all the exercices included in the type) is necessary
