[REF] mrp: backorder mechanism

Allow to "backorder" a production, meaning create another manufacturing
order with the quantity remaining to produce. We also use the
reservation of the first order on the next ones by using
`post_inventory` on the first one and moving the newly created stock
moves to the backorder.

We introduce a wizard similar to the one in stock.
Backorders have a sub-sequence.
Backorders are linked together through the procurement group.
We allow creating a backorder even if workorders are running by closing
them, the backorder will call `button_plan` and create its own.
