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}

* add an ignore file

* [fix] FSDP: handle the lazy_init better

- when state_dict and load_state_dict is called, let'em not change
  the lazy_init state.

* changelog

* longer timeout

* Revert "longer timeout"

This reverts commit 00cc145fe86210a0972a1e7ba4f37531b9e091eb.

* 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

* added changelog

* added unit test to ensure the reduce_scatter process group size is correct in default cases. And fall back to default process grouop when the reduce_scatter process group has the wrong size.
