Quick fix (maybe temporary)

Changing google/cloud/compute_v1/services/zones/transports/rest.py, line 203 from

        return compute.ZoneList.from_json(response.content)

to

        return compute.ZoneList.from_json(response.content, ignore_unknown_fields=True)

Hi @alcidesmig,

Thanks for filing an issue. It looks like this was addressed in the generator templates at googleapis/gapic-generator-python@a70b078. I've opened googleapis/googleapis-discovery#23 to bump the generator version.

Fixed by #25, will be released in the upcoming release 0.2.1. #26
