add kwargs to get_serializer_context

to add something to the context you can easily overload the get_serializer_context method. inside you have to call super to get the context, add your stuff and return it. it would save a little boilerplate if we would a take kwargs on the original method. that way the overloaded method is reduced to just the super call with the additional parameters for the context.

instead of:

    def get_serializer_context(self):
        context = super(SuperClass, self).get_serializer_context()
        context.update(dict(
            example=True
        ))
        return context


just do:

    def get_serializer_context(self):
        return super(SuperClass, self).get_serializer_context(
            example=True
        )
