The field mask of the fields in `transferJob` that are to be updated in
this request.  Fields in `transferJob` that can be updated are:
[description][google.storagetransfer.v1.TransferJob.description],
[transfer_spec][google.storagetransfer.v1.TransferJob.transfer_spec],
[notification_config][google.storagetransfer.v1.TransferJob.notification_config],
[logging_config][google.storagetransfer.v1.TransferJob.logging_config], and
[status][google.storagetransfer.v1.TransferJob.status].  To update the
`transfer_spec` of the job, a complete transfer specification must be
provided. An incomplete specification missing any required fields is
rejected with the error
[INVALID_ARGUMENT][google.rpc.Code.INVALID_ARGUMENT].
