7c07c398 - [torch.distributed.rpc] Install method docstrings from PyRRef to RRef (#40461)

[torch.distributed.rpc] Install method docstrings from PyRRef to RRef (#40461) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/40461 It turned out `:inheried-members:` (see [doc](https://www.sphinx-doc.org/en/master/usage/extensions/autodoc.html#directive-autoclass)) is not really usable. Because pybind11 generates a docstring that writes `self` as parent class, `rpc.PyRRef`, type. As a workaround, I am pulling docstrings on parent-class, `PyRRef` class, into subclass, `RRef`. And do surgery on the docstring generated by pybind11. {F241283111} ghstack-source-id: 106472496 Test Plan: buck test mode/dev-nosan //caffe2/test/distributed/rpc/:rpc_fork buck build mode/dev-nosan //caffe2/test/distributed/rpc/:rpc_fork && \ buck-out/gen/caffe2/test/distributed/rpc/rpc_fork\#binary.par \ -r test_rref_str buck build mode/dev-nosan //caffe2/test/distributed/rpc/:rpc_fork && \ buck-out/gen/caffe2/test/distributed/rpc/rpc_fork\#binary.par \ -r test_return_local_rrefs buck test mode/dev-nosan //caffe2/torch/fb/distributed/model_parallel/tests:test_elastic_averaging -- 'test_elastic_averaging_center \(caffe2\.torch\.fb\.distributed\.model_parallel\.tests\.test_elastic_averaging\.TestElasticAveragingCenter\)' P134031188 Differential Revision: D7933834 fbshipit-source-id: c03a8a4c9d98888b64492a8caba1591595bfe247
