Bug report

• Operating System:
  • Ubuntu20.04
• Installation type:
  • source build
• Version or commit hash:
  • ros2/ros2@91d8a43
• DDS implementation:
  • N.A
• Client library (if applicable):
  • rclcpp

Steps to reproduce issue

• build the following test.

int main(int argc, char * argv[])
{
  rclcpp::init(argc, argv);
  auto options = rclcpp::InitOptions().auto_initialize_logging(false);
  if (options.auto_initialize_logging()) {
    std::cout << "options.auto_initialize_logging() is true\n";
    return EXIT_FAILURE;
  } else {
    std::cout << "options.auto_initialize_logging() is false\n";
    return EXIT_SUCCESS;
  }
}

• run application

# ros2 run ros2_test_prover tmp
options.auto_initialize_logging() is true

Expected behavior

# ros2 run ros2_test_prover tmp
options.auto_initialize_logging() is false

Actual behavior

# ros2 run ros2_test_prover tmp
options.auto_initialize_logging() is true

Additional information

initialize_logging_ should be copied via constructor and assignment operator =. also it would be better to add test.
