  1. Run Docker container with a specific user. 

    Pass --user (`DOCKER_USER`) attribute when creating the container.

This has no effect in production since we are using the same user and
group than the one defined inside the Dockerfile image (docs:docs).
Although, this allow us to avoid permissions conflicts when running
the build with Docker locally (development) since we can pass our
current user.

That way, every file created/modified inside the container will be
done using the current UID and GID defined by the developer.

This can be done as,

local_settings.py
DOCKER_USER = f'{os.geteuid()}:{os.getegid()}'

With this change, there is no need to re-build the Docker image used
in production with our own custom `USER` instruction.

  2. Better default for DOCKER_USER 

    This default value will make docker build image to work without worrying about user permissions.
