Focal loss on ImageNet-LT

[MiaoMiaoYoung]

Thank you for your extraordinary work. Would you like to provide the config code (.yaml) of Focal Loss in Imagenet-LT？

I didn't write a separate config file for the focal loss. I just use the following implementation of focal loss [1] to replace the cross_entropy loss on the original baseline
