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):
File "./scripts/stop-server", line 53, in <module>
services = list_supervisor_processes(services, only_running=True)
File "./scripts/lib/supervisor.py", line 34, in list_supervisor_processes
processes = rpc().supervisor.getAllProcessInfo()

self.connect()
File "./scripts/lib/supervisor.py", line 10, in connect
self.sock.connect(self.host)
FileNotFoundError: [Errno 2] No such file or directory
```
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.
