<pre>
Run asynchronous image detection and annotation for a list of images.
Progress and results can be retrieved through the
`google.longrunning.Operations` interface.
`Operation.metadata` contains `OperationMetadata` (metadata).
`Operation.response` contains `AsyncBatchAnnotateImagesResponse` (results).
This service will write image annotation outputs to json files in customer
GCS bucket, each json file containing BatchAnnotateImagesResponse proto.
