Steps to reproduce issue
First surfaced here: https://github.com/ros2/rclcpp/pull/3192#issuecomment-4993129765
Pass an EventsCBGExecutor into a function which takes a generic rclcpp::Executor
do something in ROS land (like send a goal request to a server)
Call spin_until_future_complete on the executor
the executor hangs indefinitely
Expected behavior
The EventsCBGExecutor honors the base class interface, exercises its own spin mechanisms and doesn't indefinitely hang waiting on a future that isn't actually being exercised
Actual behavior
The future is never completed and the spin_until_future_complete call hangs indefinitely. Executor::spin_until_future_complete_impl calls spin_once_impl, which the EventsCBGExecutor does not override, resulting in the base class version being called instead (erroneously using waitsets).
