Sparsity Preserving DP-SGD in TF Privacy
Refactor model_forward_backward_pass out of compute_gradients to allow for other optimizations such as sparsity preserving noise to integrate with it.
See https://research.google/blog/sparsity-preserving-differentially-private-training/ for more details on the algorithm.
