Is this expected to be used for ros2cli profile such as ros2 topic echo --qos-profile rosout_default /rosout?

I don't familiar with the roscli code, but i think it can be used after expanding the code about parsing user input.
I will check it later.

I am not so convinced that we introduce specific default value only for rosout. instead of this, could we just specify {10, 0}?

The definition of default rosout qos profile has been moved to rcl layer, so i will close this PR. And the 722 needs you to re-check.
Besides, i have completed the rclcpp layer, i will create a new PR after the internal code-review.
