Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/86699
This diff does the following:
1. **c10d_error_logger.py**: Add an API to create a logger with a specific logging handler based on the destination.
2. The API from above would get a logging handler based on the destination provided.
- **caffe2/torch/distributed/logging_handlers.py**: For OSS, we simply use a NullHandler() for now.
3. Add associated test files for 1 and 2.
