Loader for controller "effort_controllers" not found

[lachwot]

Hi,
Apologies if this is a simple fix or a known bug, (or if I've misread the docs 😛 ), but I cant seem to run the effort demonstration that you have here in the repo (the ones via docker). I can run the position and velocity demos running fine but the effort one eventually terminates with the error [controller_manager]: Loader for controller 'effort_controllers' not found.

My understanding is that I run:

docker run -it --rm --name gazebo_ros2_control_demo --net host gazebo_ros2_control ros2 launch gazebo_ros2_control_demos cart_example_effort.launch.py gui:=false

Where we have gazebo_ros2_control_demos cart_example_effort.launch.py rather than gazebo_ros2_control_demos cart_example_position.launch.py.

I am not sure where to look to fix it (it might be the package.xml file missing the right exec_depends?)
I hope to see this demo run since I plan on implementing torque/effort controllers on 4 individual revolute joints on a rover/car model that I have in Gazebo.

Thanks in advance for any insight you can provide!

This should fix the issue #69
