[CM] Handle other exceptions while loading the controller plugin (backport #1731)

[mergify]

As of now, we are only handling the exceptions of the pluginlib::CreateClassException there are many other exceptions defined by the pluginlib, that might be also interesting to catch. I'm using std::exception as the main PluginlibException is derived from std::runtime_error and which is derived from std::exception, and this gives us way to be generic (https://github.com/ros/pluginlib/blob/jazzy/pluginlib/include/pluginlib/exceptions.hpp#L43)
