29c8b1db - [DDP Communication Hook] Rename 4 Methods of GradBucket Class (#62510)

[DDP Communication Hook] Rename 4 Methods of GradBucket Class (#62510) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/62510 `GradBucket` is an important class defined in both C++ and Python, used for PyTorch Distributed Training. We need to rename the following methods for simplicity: 1) get_index -> index 2) is_the_last_bucket_to_allreduce -> is_last, 3) get_per_parameter_tensors -> gradients, 4) get_model_params_for_bucket -> parameters. Test Plan: Local run comprehensive test with following results: https://pxl.cl/1Ml8b For two timeout failure test cases, most likely environment related and fail in my devserver.
