[Feature Request] 允许设置address规则的TTL

[uid36216]

需求应用场景 本文讨论的配置项是： smartdns: address /doubleclick.net/127.0.0.1 dnsmasq: address=/doubleclick.net/127.0.0.1

应用场景谈不上，只是用于调试。 dnsmasq有配置项local-ttl=1，默认值为0。 smartdns固定address规则的TTL=600，不受rr-ttl-reply-max的影响。

建议的方案 添加一个选项以设置address规则的TTL。 或者让rr-ttl-reply-max=1对address规则生效。

设备信息

1. 设备信息（CPU，厂家）
