Description

`CheckpointFileManager` is designed to handle checkpoint file manipulation. However, there are a few places exposing FileSystem from checkpoint files/paths. We should use `CheckpointFileManager` to manipulate checkpoint files. For example, we may want to have one storage system for checkpoint file. If all checkpoint file manipulation is performed through `CheckpointFileManager`, we can only implement `CheckpointFileManager` for the storage system, and don't need to implement FileSystem API for it.
