[FEAT]: add support OpenVPN

[vitonsky]

Description

OpenVPN is very easy to use. As linux user on KDE i can just add .ovpn file in my network manager GUI, for windows users required only install openvpn and import .ovpn file. Popular free VPN services with advertisements provide OpenVPN configs with password that reset each 24 hours.

Is you have reason why you still didn't add support of OpenVPN or you just not have time for it?

p.s. Thanks for your service, i'm not use it to save traffic for people who need it, but i like your activity
