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();
  Model response = autoMlClient.createModelAsync(parent, model).get();
  }
  </code></pre>
  
  @param parent Resource name of the parent project where the model is being created.
  @param model The model to create.
  @throws com.google.api.gax.rpc.ApiException if the remote call fails
