docs: Retrieves the list of custom images available to the specified project. Custom images are
  images you create that belong to your project. This method does not get any images that belong
  to other projects, including publicly-available images, like Debian 8. If you want to get a
  list of publicly-available images, use this method to make a request to the respective image
  project, such as debian-cloud or windows-cloud.
  
  <p>Sample code:
  
  <pre><code>
  try (ImageClient imageClient = ImageClient.create()) {
  ProjectName project = ProjectName.of("[PROJECT]");
  for (Image element : imageClient.listImages(project.toString()).iterateAll()) {
  // doThingsWith(element);
  }
  }
  </code></pre>
  
  @param project Project ID for this request.
  @throws com.google.api.gax.rpc.ApiException if the remote call fails
