Local DNS Hijacking

[MEM-917]

Hello there,
First of all, thanks for all your hard work.
The DNS interception by GFW and the latency of most ISPs made me toy with a method for intercepting DNS queries. So, I modified your own exported JSON file and it works like a charm.
If it's possible, add this feature in future releases.
The modifications are as below:

In the inbound section:

{
	"tag": "DNS-inbound",
	"listen": "127.0.0.1",
	"port": 53,
	"protocol": "dokodemo-door",
	"settings": {
		"address": "127.0.0.1",
		"followRedirect": false,
		"network": "tcp,udp",
		"timeout": 4
	}
} 

In the outbound section:

{
	"tag": "DNS-outbound",
	"protocol": "dns",
	"settings": {
		"network": "",
		"address": "1.1.1.1",
		"port": 53
	}
}

In the routing:

{
	"type": "field",
	"inboundTag": [
		"DNS-inbound"
	],
	"outboundTag": "DNS-outbound"
}
