Improve location browsing
With the implementation of #4901 (closed), the browsing of large location tree may become difficult.
We need to show the childs on the form view.
But it is not enough, the "Location Quantity" will not work expand and there is no form view. I do not think we should add a form view because it will not really be useful for the usage of this view. Indeed user who are going to use this view may have two purpose:
- have quick number about the quantities per warehouse or main locations;
- search where are the products.
As the second case is not manageable in a large tree view, I propose to have two relate the current one and a new one which use a list view instead of a tree.
