Monitor metric not found for Learning Schedulers when using Result()

[AxlAlm]

🐛 Bug

If you are using Result() (TrainResult() and EvalResult()) you cannot use a Learning Scheduler that monitors a metric as it will not find the metrics logged/stored by the Result() class. The available metrics for me that are listed below in the error are not the ones that exist in my TrainResult() and EvalResult().

either the update_learning_rates() function in training_loop.py is not looking in the right place for metrics or the Results() metric aggregation/updating is not updating in the correct places.

Am i right or am i doing something wrong?
