as titled, this PR expose this dunder method as a public API in the doc,
so that different checkpoint implementations can leverage this protocol,
instead of exposing a separate API
Pull Request resolved: https://github.com/pytorch/pytorch/pull/144100
Approved by: https://github.com/awgu
ghstack dependencies: #144099
reland of https://github.com/pytorch/pytorch/pull/133113
I have to create a new PR because the previous reverted PR could not either be rebased, or imported successfully :(
----
Moving DTensor to be in the public namespace, to formally add the documentation page that includes all the public APIs. This includes:
* many path renames and path import fixes
* a dedicated doc page without too much content yet (adding in the next PRs)
* To preserve the BC for users still using the torch.distributed._tensor, I added a shim script to redirect old path calls to the new module
The BC preserving is evidented by the fact that all DTensor tests are still working without changing the public imports. So it's safe to land the changes
