API 2.0 : Users : UserDTO schema does not flag all required fields

Issue Summary

Fields divisionId, regionId, cityId and costCenterId are mandatory in Users (UI and API), but the Swagger UserDTO schema doesn't reflect that.

Steps to Reproduce

1. Browse to Swagger then expand UserDTO schema
2. Notice that divisionId, regionId, cityId and costCenterId does not have the required attribute
3. They're also flagged as nullable: true

Expected Results

• The fields divisionId, regionId, cityId and costCenterId have the required attribute
• The fields divisionId, regionId, cityId and costCenterId does not have the nullable: true attribute
• PdM to confrm

Actual Results

• The fields divisionId, regionId, cityId and costCenterId does not have the required attribute
• The fields divisionId, regionId, cityId and costCenterId have the nullable: true attribute

Workaround

• Currently there is no known workaround for this behavior. A workaround will be added here when available.
