[IMP] rma_sale: prepare kits integration

When a sale line has a phantom product (mrp kits) the RMA would not be
possible as the wizard couldn't pair the components moves with the
product in the line. With this approach, we can at least return the
spare components of the original kit line.

We also need some hooks to intervine in the main methods, like in
invoicing.
