I update the initialisation process (that was empty before).
I create the different folders to host the logs, cache and others.

I create a symbolic link for the following:

- a run-allgo script that instanciate the Django app and Nginx
- supervisor configuration (at the moment, commented)
- nginx configuration

I then execute the run-algo script. At the moment, it seems that the
execution of this script either doesn't occur or create an error with
docker compose at launch (the dev-django container doesn't run). So at
the moment, I run by hand the script once the container is up.
