[IMP] stock: alert in case of rescheduling

In a move chain, if the scheduled date of a move N is updated, we would
like to create an alert on the move N+1.

This commit adds a boolean field on stock.rule that, if set to True, will
create a next activity on the stock.picking of the move that are created
from this rule, in case the previous move has its scheduled date changed.

The message will depends on the propagation of the schedule date between
the two moves:
 - If the date is propagated, the message informs the picking user that
  the transfer is delayed.
 - If the date is not propagated and the new date of move N is after the
   schedule date of move N+1, the message says that the scheduled date
   will be outdated.
