* [FSDP] Add an arg for FSDP __init__

Add an arg, disable_reshard_on_root, for FSDP __init__ to handle the following issue
https://github.com/facebookresearch/fairscale/issues/878


For some cases (models wrapped by autowrap), the parameters (of root modules) needs to be sharded, and reshard_after_forward should not be set to False.
"disable_reshard_on_root" is for users to choose whether to force reshard_after_forward of root modules to be False or not.

* Update fully_sharded_data_parallel.py

Modified the description of the feature to explain more clear.

* Update fairscale/nn/data_parallel/fully_sharded_data_parallel.py

* Modified the comments

Modified the comments of disable_reshard_on_root

* Add a new argument for OSS __init__

Add a new argument for OSS __init__ to force the OSS to apply "_broadcast_object" for rebuilding the sharded optimizer. For more details, please see https://github.com/facebookresearch/fairscale/issues/937

* update pytest versions

* [test] test related changes

- upgrade to newer pytorch versions
- added function to make test more deterministic on A100 and TF32
- fixed some tests so that they are correctly skipped on a single GPU system

* more fixes

* formatting overly long lines

* format

* better test without trigger a warning

* fix an optim state bug with newer pytorch

- adam optimizer seems to return "step" as a singleton tensor now in the
nightly build
- this fixes it assumeing non-tensor value can still be loaded back by
the optimizer

* improve oss.py

- use min_loss for regression checking is a bit more reliable
- also increased the num epochs from 10 to 12

* small oss.py fix

* Update fairscale/nn/data_parallel/fully_sharded_data_parallel.py
