Enforce usage of lost and found on inventory
Normally inventories should always use the same lost and found location.
Users may create other lost_found location for different purpose than inventory like to scrap products.
But in the case where there are multiple lost_found location, the user has to choose but it is not the role of the inventory man.
Also one could want to have different lost_found for inventory per warehouse in order to detect/evaluate which warehouse is loosing more.
So I propose to remove the lost_found on inventory and to define one per warehouse.
