CRUD controller's index action should use paginate instead of all

I have a Products CRUD controller that seems like:

```
public function index(Request $request)
    {
        $products = Products::all();

		return view('admin.products.index', compact('products'));
	}
```
In this way a serious performance issue should be occurred with large data models. I think it will be better if `::paginate()` used instead of `all()`
