Subject: [PATCH]  [IMP] product: find best price for a vendor based on min
 qty.

Purpose of this task:
Choose a vendor with the minimum price, respecting the quantity
Before commit:
The system was choosing the vendor by sequence,
But if there are any vendor having a different price for the same product,
based on ordered quantity, then the system can't choose the lowest price.
After this commit:
If there are vendors having different price based on the ordered quantity,
then the system will choose the vendor based on the quantity and lowest price.
