Feature description

The rclcpp NodeOptions class has a rosout_qos field that allows you to set the QoS policy for when the node publishes to /rosout as part of ROS logging. The rclpy Node constructor has no such option, so python users are stuck with the default rosout_qos, which is unsuitable for some applications (we're experiencing dropped log messages that can be resolved for cpp nodes by adjusting the rosout_qos).

Implementation considerations

An additional parameter in the Node constructor would work perfectly well, and would just need to get passed to rcl here
