CloudDataTransferServiceS3ToGCSOperator does not support identify federation

[lalmgren]

Description

We are using identity federation to pass access from GCP to AWS. However, it is not possible to use identify federation with CloudDataTransferServiceS3ToGCSOperator as AWS_S3_DATA_SOURCE is using ACCESS_KEY_ID and SECRET_ACCESS_KEY. Maybe it should be possible to pass AWS_S3_DATA_SOURCE?

Use case/motivation

To enable using identity federation between GCP and AWS I'd like it to be possible to pass AWS_S3_DATA_SOURCE to the operator.
