       does this need to actually sleep or could it just add 100, 200, etc to the updated time on the `StorageObject`.

Review comment:
       there is a similar check being done in `ObjectStorageIterator.advanceStorageObject`, though this one looks like it might be better at picking up more stuff that Druid probably doesn't want to see, maybe this method should be moved to `GoogleUtils` or somewhere and shared?

Review comment:
       nit: this would maybe be a little cleaner to make a `CloudObjectLocation` directly from the `URI` for the base location to re-use the URI parsing stuff that is used in other places
   
   ```suggestion
         final CloudObjectLocation baseLocation = new CloudObjectLocation(descriptorBase);
         final Objects objects = storage.list(baseLocation.getBucket()).setPrefix(baseLocation.getPath()).setMaxResults(MAX_LISTING_KEYS).execute();
   ```

Review comment:
       In most other docs, we shorten Google Cloud Storage as `GCS`, could we do that here to be consistent?
