> At least for publishing (and maybe pulling) messages, non-Dataflow-based sources and sinks for Pub/Sub use the [public API|https://cloud.google.com/pubsub/docs/publisher] for Pub/Sub, which doesn't support id_label and timestamp_attribute settings.
> Publishing:
>  id_label - add an attribute to each message with a unique value
>  timestamp_attribute - add an attribute to each message with the publishing time as its value
> Pulling:
>  id_label - use the value of this message attribute to deduplicate messages
>  timestamp_attribute - use the value of this message attribute as the element's timestamp
>  
> Implementation details: could probably create a pubsubio.py module, for reuse with other runners (i.e. implement Pub/Sub IO as PTransforms and not NativeSinks and Sources).
