Key as the identifier of Address at Customer Import endpoint

The Customer Import endpoint is enabled again. We have made the changes below. You will receive proper 2XX responses for valid API requests. We apologize for the inconvenience we may have caused.

The Customers Import endpoint now uses key of an Address as a mandatory identifier for Addresses, and id is no longer a supported identifier. Said differently, the addresses field in CustomerImport now takes the CustomerAddress type, replacing the previous Address.

The following changes were made:

• addresses in CustomerImport is now a required field. (It can, however, be an empty array.)
• added CustomerAddress.
