ProcessGroupNCCL should respect timeout passed in to init_process_group. (#27224)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/27224
As part of adding error handling to NCCL, we are now able to specify a
timeout for operations using ProcessGroupNCCL. Although, this timeout had a
default of 10 seconds and didn't respect the timeout specified in
init_process_group.
In this change, I've ensured we pass the appropriate timeout to
ProcessGroupNCCL.
