torch.init_process_group includes a default 30 minute timeout.
```
While the worker is listening for instructions, after thirty idle minutes an error gets thrown:
[1] is setting up NCCL communicator and retrieving ncclUniqueId from [0] via c10d key-value store by key '0', but store->get('0') got error: Socket Timeout

After this error, any attempt by the worker to reconnect and establish a
new session with the master fails. Including pod restarts. Trying to
establish any new connection from worker is met with this error:
```

master_addr is only used for static rdzv_backend and when rdzv_endpoint is not specified.

Cleaning up the process group and reinitalizing on the worker side does
not resolve this issue either. The state between the worker and master
is inconsistent, requires a master restart.
The best solution here is increasing the timeout to prevent the
connection from being closed. I have included a dockerfile fix here.
