Improvements to ssd_offload to support pickling/unpickling SsdTensorHandle (and derived classes) (#964)

Verified that FSDP wrapped models using ssd_offload checkpoint save and restore correctly

This is no longer needed since isort's version is 5.10

Also fix black version to 22.3.0 to fix issue with click
dependency.

Update files that now fail with new version of black {a = 2 ** 4} ->
{a = 2**4}

* [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 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

- this fixes it assumeing non-tensor value can still be loaded back by
the optimizer

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

* small oss.py fix
