Create CT using PVE UI and Slackware template

[bobgrayx]

Hello to all,
I have written a Perl code which facilitate to create a slackware container using template from https://images.linuxcontainers.org/ and PVE UI. So now I would like to share it in case it can be added to the source code for future updates. I am actually using it since version 8.1 of PVE but updates ruin it couple of times.. so now it works on 8.2.4

Attached archive contains Perl package file which should be in PVE/LXC/Setup/ directory. The code in it use the collected information from the PVE UI (IP, hostname, net mask, gateway..) to create new container. Currently you can use only Slackware 15 templates and newer.
The code prints few debug lines which can be easily removed!

Regards,
Bob
