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:

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.
