If `zulip-puppet-apply` is run during an upgrade, it will immediately
try to re-`stop-server` before running migrations; if the last step in
the puppet application was to restart `supervisor`, it may not be
listening on its UNIX socket yet. In such cases, `socket.connect()`
throws a `FileNotFoundError`:
```
Traceback (most recent call last):

```
Catch the `FileNotFoundError` and retry twice more, with backoff. If
it fails repeatedly, point to `service supervisor status` for further
debugging, as `FileNotFoundError` is rather misleading -- the file
exists, it simply is not accepting connections.
