How to change/modify learning scheduler when use BaseFinetuning?

[ZeguanXiao]

When doing transfer learning, we not only want to change the learning rate between phases but also to reinitialize lr_scheduler. While this comment gives an example to introduce a new lr_scheduler, trainer.new_schedule() seems not a valid API. And it is better to be compatible with the LearningRateMonitor callback.

Is any workaround to do this?
