    Add *args, **kwargs to ModalBackdropMixin's init method

    Before this change ModalBackdropMixin called super(...).__init__()
    without arguments. This imposed restrictions on what classes this
    mixin could have been mixed into, i.e. only classes, that do not accept
    any parameters.
    This proved to be a problem for murano-dashboard, since it uses this
    mixin (indirectly through ModalFormMixin) and mixes it into a class,
    that accepts parameters to it's init method.
    This change allows to use ModalBackdropMixin with classes that have
    init methods with parameters.
