[IMP] (purchase_)stock: suppliers information in replenishment

Infobox to help the user with the replenishment. Allow those actions:
- See the different supplier with their lead time, price and quantity
- Be able to select a supplier and set it on the orderpoint
⁻ See the last delivery by mmonth for the product
- Last purchase date for each supplier

Technicaly it use a wizard and a fields char with JSON used by
a widget to display a static template. Also it creates directly
the wizard in backend instead of just let the view manage the new
object since we need a button on a one2many and if the records do
not have an id, it's not possilbe to use it.
