Option to specify shutdown for PM2

[npburns224]

Describe The Bug:
Homebridge Config UI X not honoring custom shutdown command specified in the config.json file. Pressing the "Shutdown" button on the web interface runs the specified custom reboot command.

To Reproduce:

1. Insert "linux": { "shutdown": "pm2 stop", "restart": "pm2 restart" } into config.json.
2. Restart Homebridge instance.
3. Press "Shutdown" button on web interface.

Expected behavior:
pm2 stops Homebridge instance.

Snippit from pm2 Log:
| Homebridge-MQTT | [Config] Shutting down linux server with command: "pm2 restart"
| Homebridge-MQTT | [Config] Got SIGINT, shutting down Homebridge...
| Homebridge-MQTT | [Config] Loaded config.json with 0 accessories and 3 platforms.
[Homebridge continues to run from this point]

Homebridge Config:

{
            "platform": "config",
            "name": "Config",
            "port": 8084,
            "auth": "form",
            "theme": "dark-mode",
            "linux": {
                "shutdown": "pm2 stop",
                "restart": "pm2 restart"
            },
            "temp": "/sys/class/thermal/thermal_zone0/temp",
            "tempUnits": "c",
            "sudo": false,
            "log": {
                "method": "custom",
                "command": "pm2 logs --out --lines 50"
            }
        }
