[Propose] [WIP] - SimpleReorderOperation, when you need a simple way to order items

[susanu]

WHY

I have some items that need to be sorted in a specific way, this is controlled by a single column in the database called order.
I tried the classic ReorderOperation but it works only with multiple columns.
I just want a dumb, simple ordering, no levels, no trees.

Works similar to ReorderOperation, have the same configuration with a small change.
NOTE: Use either ReorderOperation or SimpleReorderOperation

Example:

protected function setupReorderOperation(): void
{
    CRUD::set('reorder.label', 'product.name');
    CRUD::set('reorder.column', 'order');
}

What is different:
Removed following settings:

• max_level
• reorderColumnNames

Added following settings:

• column -> the db column that is used to sort the items

Let me know your thoughts.
