Add Difficulty column to Questions

[Matthew M-B]

Please add the difficulty column (string) to the questions model. Please also update the corresponding serializers so that difficulty can be accessed via its corresponding endpoints.

On the model, use the following syntax to ensure the difficulty can be of the following options: Easy, Medium, and Hard.

format = models.CharField(
        choices=(
            ("t", "text"),
            ("h", "html"),
            ("m", "mathjax"),
        ),
        max_length=1,
    )

Hi @MathyouMB - can myself or @aidutcher take this? We are peer programming together. I would submit the PR with credit to him.
