hey @iuhilnehc-ynos, thanks for working on this! is this ready? I could give it a quick test for my application and give feedback

[iuhilnehc-ynos]

@tonynajjar I have some other PRs in my hand. I suppose that another one, which was pushed before this PR, will be reviewed in the coming days. Therefore, I marked this PR as a draft.

I would appreciate it if you could give it a try. Any feedback is welcome.

I'm on Humble so I just copied your changes to to_parameters_list.py and that did the trick! With this PR, my composable node was able to read a yaml file as such:

/**:
  controller_server:
    ros__parameters:
      speed_limit_topic: "speed_limit"
      odom_topic: odometry/filtered
