Add a manage.py and check for the python version

    Add a script called manage.py which will replace install.sh
and handle the options needed for managing the development
environment.

    Currently, manage.py checks if the python interpreter is correct
and display an error if not.

    You can now install the virtualenv and the requirements with the
manage file:
    ./manage.py install [option]
        options:

            -t: install tests requirements
            -r: install dev requirements
            -v: install python virtualenv
    The manage file is provided with an help:
        ./manage.py [-h, --help]
    The install command is also provided with an help:
        ./manage.py install [-h, --help]

            -c: clean docker runtime (stop and remove containers)
            -r: run the dedicated docker container
    The manage file is provided with an help:
        ./manage.py [-h, --help]
