Should we support random operation of PyTorch Tensor

Hi @wyli @ericspod @rijobro ,

Currently, all the random operations in transforms are based on numpy, especially for deterministic purpose.
Most of them are light computation, but some are heavy to generate a random array, for example:
https://github.com/Project-MONAI/MONAI/blob/dev/monai/transforms/intensity/array.py#L1910
It may block the GPU Tensor transform.
Should we consider to support Tensor random operations?
What do you guys think?

Thanks.
