Convert orphan files deletion task to async using celery task. Update celery config to make it possible

[Didayolo]

Original PR

• convert orphan files deletion task to async using celery task. Update celery config to make it possible #1597

Description

Make the orphan files deletion task asynchronous.
This comes with few changes to make it possible:

• Enable the backend results of the celery tasks. This allows to store the states of any celery tasks. We use this to check is the task is running or not
• upgrade the celery package to the closest version that fixes a known bug on incompatible version with python 3.9 that manifests only when working with celery task results
• Fixes the patch number of the python version in the Dockerfile to match the one in the pyproject.toml file (else poetry won't be happy)
• Add an API route to check the status of the orphan files deletion task
• Update the frontend to reflect the status of the deletion task

For testing

Do not forget to build the docker images !

@OhMaley Error during the building:

Any thoughts?

Oui il faut que la version de python noté dans le Dockerfile et dans pyproject.toml soit identique.
Je l'ai update dans le dockerfile pour être la même version que celle du pyproject.toml, mais ce dernier fichier a été mis à jour il y a 4h on dirai. Il faut donc mettre à jour le dockerfile

Ce qui m'étonne c'est que je suis reparti de develop à l'instant. Mais ça devrait être bon maintenant j'imagine.
