Run asynchronous image detection and annotation for a list of images.

<p>Progress and results can be retrieved through the `google.longrunning.Operations` interface.
`Operation.metadata` contains `OperationMetadata` (metadata). `Operation.response` contains
`AsyncBatchAnnotateImagesResponse` (results).

<p>This service will write image annotation outputs to json files in customer GCS bucket, each
json file containing BatchAnnotateImagesResponse proto.

<p>Sample code:

<pre>{@code
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in
// https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
try (ImageAnnotatorClient imageAnnotatorClient = ImageAnnotatorClient.create()) {

}
}</pre>

@param requests Required. Individual image annotation requests for this batch.
@param outputConfig Required. The desired output location and metadata (e.g. format).
@throws com.google.api.gax.rpc.ApiException if the remote call fails
