B-21474

Summary

Adds the ability to use DTOD to calculate mileage if either destination or pickup addresses are OCONUS to support calculation of RDD

###Setup
A breakpoint is required for the following lines
pkg/services/mto_shipment/mto_shipment_updater.go:1226
pkg/services/mto_shipment/mto_shipment_updater.go:1228

How to test

[important] Debugger must be enabled as RDD is not currently displayed

1. Create a new customer with a new HHG shipment. One of the addresses in the shipment should be Alaska
2. Submit shipment as SC like normal, approve the shipment as TOO
3. Update the shipment as a Prime user with all required fields, including a weight.
4. In calculate CalculateRequiredDeliveryDate verify that the country is being populated for both the addresses on lines 1208 and 1216
5. With the breakpoints set step through the statements and verify useDTOD is set to true before planner.ZipTransitDistance is run
6. step through planner.ZipTransitDistance and verify that DTOD is called to calculate the mileage
7. verify that a nonzero mileage is being returned for planner.ZipTransitDistance
