rogpt1: TypeError: DSElasticAgent._set_master_addr_port() takes 3 positional arguments but 4 were given
```

**The reason**
PyTorch will use four arguments to call function
[_set_master_addr_port()](https://github.com/pytorch/pytorch/blob/e732adf0a7f31159dc827e563106279bf969144a/torch/distributed/elastic/agent/server/api.py#L513)
but the "_set_master_addr_port()" of "DSElasticAgent" only implement
three arguments.

**The solution**
Add the last "local_addr" argument by following PyTorch. And, to avoid
changing the current behavior, set its default value to "None".
