Preferring dash over underscore in command-line options. Add `--command-arg-name` to the argument parser. The old arguments with underscores `--command_arg_name` are kept for backward compatibility.
Both dashes and underscores are used in the PyTorch codebase. Some argument parsers only have dashes or only have underscores in arguments. For example, the `torchrun` utility for distributed training only accepts underscore arguments (e.g., `--master_port`). The dashes are more common in other command-line tools. And it looks to be the default choice in the Python standard library:
`argparse.BooleanOptionalAction`: 4a9dff0e5a/Lib/argparse.py (L893-L895)
```python
class BooleanOptionalAction(Action):
def __init__(...):
if option_string.startswith('--'):
option_string = '--no-' + option_string[2:]
_option_strings.append(option_string)
```
It adds `--no-argname`, not `--no_argname`. Also typing `_` need to press the shift or the caps-lock key than `-`.

Summary:
It turns out my lint doesn't work on CI all the time because of shell differences. I'm working on a new more comprehensive lint in https://github.com/pytorch/pytorch/pull/66826 and it'd be nice if these could be cleared first.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/63442
Continuation of https://github.com/pytorch/pytorch/pull/62051, I've
enabled elastic and launcher tests to run in opt-asan mode which is supported
with spawn multiprocessing.
This allows us to completely get rid of fork based tests from torch.distributed
and have all tests run in spawn mode.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/61887
1) Introduced a `sandcastle_skip_if` decorator that ensures these
tests just get passed on sandcastle.
2) Fixed all test files under `test/distributed` to not use `unittest.skip`
Overall goal is to avoid using skips since sandcastle tags these tests as
continuously skipping.
