Consider Pagination parameter `modifierClass` to be actual modifier for the rest of Pagination class-related params

[LeTraceurSnork]

Clear and concise description of the problem

Pagination module now has bunch of parameters such as paginationDisabledClass, horizontalClass, hiddenClass, etc.
But at the same time there is parameter modifierClass that semantically should be a prefix to all of them.

Suggested solution

So my suggestion is: if modifierClass is overriden, but the other params isn't, they will substitute modifierClass as their prefix, like below:

const swiper = new Swiper($slider[0], {
    modules: [Pagination],
    pagination: {
        modifierClass: 'foobar',
    },
});

And that would do the same as if you call it now as such:

const swiper = new Swiper($slider[0], {
    modules: [Pagination],
    pagination: {
        modifierClass: 'foobar',
        hiddenClass: 'foobar-hidden',
        paginationDisabledClass: 'foobar-disabled',
        ...,
        verticalClass: 'foobar-vertical'
    },
});
