Review comment:
Should we mention the number of retries and exponential back-off in the docs somewhere? I am not sure about that one. I think we are not mentioning it elsewhere (assuming that the hard-coded values are reasonable). But maybe (possibly in a separate PR) we could make it more explicit on the typical retry scenarios we use for GCP classes? Or maybe we should make it somehow configurable for all GCP classes ? WDYT @turbaszek @mik-laj ?
