VPN provider support: Smartdnsproxy

[jdubb2]

SmartDNSProxy-OpenVPN-2.zip
One of the following is required:

• Publicly accessible URL to a zip file containing the Openvpn configuration files
• Publicly accessible URL to a structured (JSON etc.) list of servers and attach an example Openvpn configuration file for both TCP and UDP
• Publicly accessible URL to the list of servers and attach an example Openvpn configuration file for both TCP and UDP

If the list of servers requires to login or is hidden behind an interactive configurator,
you can only use a custom Openvpn configuration file.
The Wiki's OpenVPN configuration file page describes how to do so.
