fix(ts3server): Monitor command fails, if query_ip is set to a loopback IP

[drantor]

Description

Fix monitoring failing and restarting the teamspeak server, if the query interface is bound to a loopback IP. I didn't want to remove the logic for filtering loopback IPs, so I just added fetching the query_ip from the ts3server.ini and using that one as queryips in check_ip which then will be used in command_monitor. I also added the other configurable teamspeak IPs as variables, even if they currently have no use.

Background

I don't want remote users to connect to the teamspeak query interface, so I bound it to 127.0.0.1. With the 21.5.0 Release ts3 got added to info_game and the monitor command is now checking the query port, but check_ip is filtering 127.0.0-IPs, so the monitor command was failing for me every time. I'm not 100% certain that this is the cause but it started after the update-lgsm cron had run, and this are the only changes where I could see a effect on ts3server.
