Request: Send a command in the console

[Fede445]

Request:
The ability to send commands in the console before the restart, such as messages, would be nice.
For example, if I wanted to backup the server before the restart, the command is sent a few minutes before to start the backup.

"messageList": [
    {
      "time": 900,
      "message": "Server restart in 15 minutes"
    },
    {
      "time": 300,
      "message": "Server restart in 5 minutes"
      "command": "ebackup backup"
    }
  ],

In this case, 5 minutes before restart, in addition to sending the notification to the players also sends a command in the console to start the backup of the server through, in this case, the ebackup plugin.
