Description

Currently, when creating a google_storage_transfer_job resource, it supports specifying a aws_s3_data_source to migrate files from S3 to GCS.

However, even though there are documented means to do it via the REST API, there is currently no documented way for us to pass the CloudFront distribution domain name to the provider. Supporting this feature will definitely ease any data migration to GCP as it will help to minimize data transfer costs incurred on AWS and potentially give us quicker data transfers.
