Add option to proxy DNS requests via SOCKS

[ghost]

Is your feature request related to a problem? Please describe.
Currently, DNS is resolved directly, not through the SOCKS5 proxy.
This causes DNS leaks when chaining with other VPN services.

Describe the solution you'd like
I think the hostname needs to be passed to the SOCKS server without DNS resolution.

You can already use the port forwarding option to secure ports with tools like Nebulo. See here: #201

I don't mean DoH or DoT, but DNS resolution through a socks proxy.
Because, even with DoH or DoT, DNS is resolved without going through a proxy (VPN), which causes DNS leaks.
DNS leaks allow tracking.

I think this is covered by tools like Invizible Pro.

OK, thanks.
