Deepgrow `Interaction` is not compatiable with `decollate_batch` for v 0.6.0 (8/July)

[yiheng-wang-nv]

Describe the bug
In deepgrow tutorial (https://github.com/Project-MONAI/tutorials/blob/master/deepgrow/ignite/train.py#L201), we can see there are two groups of transforms: pre_transforms and click_transforms, and click_transforms will be used in monai.apps.deepgrow.interaction.Interaction. So far, this way is not compatiable with our decollate_batch logic.
