This PR enables BF16 data type support for CIFAR10 training example. The following changes are added:

  1. Support the case that bfloat16 is turned on in ds_config.json
  2. Fix compatibility issues with latest Pytorch, where dataiter.next() is no longer supported by Pytorch
  3. Use accelerator abstration interface to allow run this example on other accelerators.

Hi @conglongli , can you review this PR? This PR enables CIFAR10 and HelloDeepSpeed training for non-CUDA devices i.e. CPU training. Thanks!

* support bf16 and CPU accelerator

* support both bfloat16 and fp16 data type

* change default data type to bf16 to help run this demo on both CPU and GPU

* enable HelloDeepSpeed for non-CUDA device

* revert changes for sh output

* allow select bf16/fp16 datatype

* revert unnecessary changes

* seperate bf16 and fp16 config
