[IMP] product_expiry: Add delivery slip expiration dates

This commit adds the option to have lot/serial number expiration
dates be included in a delivery report (via settings). This is only

lot/serial numbers are used, and 1 or more lot/serial number expiration
dates exist.

This completes subsection 4 of overall Improve delivery slip task.
