Implement an option to "Route all traffic through Tor"

Created by: SunilMohanAdapa

The idea is that all the traffic forwarded through FreedomBox will then be routed through Tor transparently. Software that does not have SOCKS proxy support will also work this setup. It also make client application configuration easier (by eliminating it). Tor wiki describes this setup.

It should setup

• Update Tor configuration
• Restart/reload Tor
• Show status of such functionality
• Setup Firewall rules
• Setup DNS through Tor etc.
