Parameters not working in Iron through cli

[rosterloh]

Describe the bug
Using get|set|dump from the ros2 cli fails with Wait for service timed out waiting for parameter services for node /micro_ros_node. If you attempt to get or set parameters in code this works successfully.

To Reproduce
Steps to reproduce the behaviour:

1. Create micro-ROS application with parameter server like this
2. Connect the agent
3. Run ros2 param dump esp32_param_node
4. See error Wait for service timed out waiting for parameter services for node /esp32_param_node

Expected behaviour
ros2 param cli commands work as expected the same as non micro-ROS nodes

System information (please complete the following information):

• OS: Ubuntu 22.04
• ROS 2 Iron
• Version 4.0.3

Hey @rosterloh, we are currently releasing and testing Iron for micro-ROS, the official release is not already out.

@pablogs9 I completely understand. I just saw you were working on it so I thought I'd bring it up while you were busy. I'd happily help test or work on anything for you if it helps.

[Acuadros95]

We were missing a parameter service on the micro-ROS client side, that is the reason for the Wait for service timed out waiting for parameter services message.

@rosterloh Thanks for checking this! This PR will solve the issue: ros2/rclc#354

Amazing thanks @Acuadros95!

Closing as ros2/rclc#354 is merged!
