> CONFIG proxy.config.dns.nameservers is the nameserver specified to TS, but it does not take into effect without setting of proxy.config.dns.round_robin_nameservers.  please refer file DNS.cc: DNSProcessor::dns_init
> and even if setup proxy.config.dns.round_robin_nameservers, the nameserver setting from system default  /etc/resolv.conf is take into active.
> as the SplitDNS have separated file to config, we should make some clear usage of this proxy.config.dns.nameservers and system default config.
> I think proxy.config.dns.nameservers is a setting to let TS use dedicate DNS server for it, and if all that hosts failed, we then use system default. if they specify proxy.config.dns.round_robin_nameservers too, then we use rr mode in all NS servers.
