fix: pass the timeout when we are waiting a node to start

Thsi fix a bug that was reported with slower machine
the core lightning is not fast enought to start and
so it fails.

This PR allow to pass a custom timeout to the wait_for function.

```
self = <pyln.client.lightning.UnixSocket object at 0x7ff95de096c0>

    def connect(self) -> None:
        try:
            self.sock = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
>           self.sock.connect(str(self.path))
E           FileNotFoundError: [Errno 2] No such file or directory
