Problem handling local structured property kind without keys #627
Description
According to: https://cloud.google.com/appengine/docs/python/ndb/properties#structured
Local structured properties do not require keys and AppEngine appears to be fine with this.
Unfortunately, the gcloud-python library expects keys for every entity, even if they're local structured ones.
My work around is to update my entities in AppEngine to provide dummy keys, however, it would be nice if the library supported it natively.
