DNS Resolution service

This is how I was going to handle it:

func NewTorResover(proxy string) *madns.Resolver {
	return &madns.Resolver{
		Backend: &net.Resolver{
			PreferGo: true,
			Dial: func(ctx context.Context, network, address string) (net.Conn, error) {
				d := net.Dialer{
					Timeout: time.Millisecond * time.Duration(10000),
				}
				return d.DialContext(ctx, network, proxy)
			},
		},
	}
}

With:

tor.StartConf{
		ExtraArgs:       []string{"--DNSPort", "2121"},
}

And then you can set the global libp2p name resolution using:

madns.DefaultResolver = NewTorResover("localhost:2121")

Not a big fan of global vars but without any changes to libp2p I'm not sure there's a better way. Downside is this does not resolve TXT records as far as I can tell.

I'm not a big either, I guess we can create a DNSResolverOption in the libp2p basic host, and ensure routed/circuit host use the underlying basic host for that.
