* add support for predivide as a flag
* add predivide json config, remove allgather_disable (as it's not currently used anymore)

Contiguous Gradients should be set to false by default. Its not useful unless the model is very large

* Fix for CPU memory Bloating Issue caused by pyorch backward graph creation in allgather. Fixed by calling detach on tensors before calling all_gather

* adding BingSqaud e2e test

* updating the draft test; bring final step under try section

* finalizinf test for base deepspeed and deepspeed with ZeRO

* applying the comment (thanks Jeff); fixed formatting

* Support dynamic loss scale args in fp16 optimizers

* Update names

* add basic post-install test

* update apex version to feb 5th commit

* use gradient clipping instead of max grad norm in tests

* add warning when user provides max_grad_norm

* update examples commit

1) CSR parameter names should end with .weight. 
2) When using basic optimizer directly, DeepSpeed should handle zero_grad. Letting the basic optimizer do the zero_grad resulted in residual gradients in the embedding layer due to unknown reasons.
