84df182f - Add log_key_prefix to Trainer to control the prefix for metrics like epoch (#21784)

Add log_key_prefix to Trainer to control the prefix for metrics like epoch (#21784) feat: add log_key_prefix to Trainer for Trainer-generated metric keys Adds a `log_key_prefix` parameter to `Trainer` that prepends a string to Trainer-generated metric keys such as `epoch`. Defaults to bare `epoch` (no prefix), so existing users see no change. Co-authored-by: Bhimraj Yadav <bhimrajyadav977@gmail.com>
