Sale Owner Stock Sourcing

This module allows you to choose for every sale order line the owner of the stock that will be dispatched. By choosing an owner, the generated deliveries will then look for stock belonging to the specified partner. If none is available, then the picking will be waiting availability until stocks with proper ownership are replenished.

Specifying an owner on a line forces to use the stock of this owner. Leaving the owner empty allows to use stock (quant) without owner.

Note: pickings and moves both have an owner field. Here we only propagate the owner to moves. We have integration tests that check that this does end up with the correct reservation of quants, even if two order lines have different owners. If we decide instead to propagate the owner_id field of the picking as well, we will have to split pickings accordingly in case a sale order has lines with different owners.
