Automatically create iptables rules for UI and main/child bridges
### Current Situation

I use `ufw` with my Ubuntu server and currently need to manually open up ports for the UI and the main/child bridges:
```bash
sudo ufw allow 8581/tcp               # UI
sudo ufw allow 36149,41388,59102/tcp  # Main and child bridges
```

### Proposed Change

Homebridge could look up the ports used by the UI, main bridge, and child bridges, and automatically add/update corresponding `iptables` rules so that users don't need to add them manually to their firewall.
