The bucket_attributes_view and bucket_attributes_latest_snapshot_view tables in Storage Insights datasets are updated with two new fields

## Feature The `bucket_attributes_view` and `bucket_attributes_latest_snapshot_view` tables in [Storage Insights datasets](https://cloud.google.com/storage/docs/insights/datasets) are updated with two new fields: `objectCount` and `totalSize`. `objectCount` reflects the total number of objects in the bucket and `totalSize` reflects the total size of the bucket in bytes. The tables are automatically updated with the new fields in all existing datasets and are included in all new dataset configurations.
