docs: Creates a model. Returns a Model in the [response][google.longrunning.Operation.response] field
  when it completes. When you create a model, several model evaluations are created for it: a
  global evaluation, and one evaluation for each annotation spec.
  
  <p>Sample code:
  
  <pre><code>
  try (AutoMlClient autoMlClient = AutoMlClient.create()) {
  LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
  Model model = Model.newBuilder().build();
  CreateModelRequest request = CreateModelRequest.newBuilder()
  .setParent(parent.toString())
  .setModel(model)
  .build();
  Model response = autoMlClient.createModelAsync(request).get();
  }
  </code></pre>
