Instead of having a module handle the procurement_jit, we now
incorporate it directly within sale_stock._action_launch_stock_rule and
make it dependent on the new stock.picking.type reservation_method option
rather than applying to all deliveries.
Note that only picking scheduler trigger has been moved to sale_stock,
since the action_assign portion of its moves are now handled directly in
stock.move.
Also we add a new test to ensure new reservation_method logic works
as expected with sale orders.
