The ability to register more than 2 DNS servers

[kartavenko1983]

Please implement the ability to specify more than 2 DNS servers, both during initial configuration and adding them if necessary. It is also necessary that these dns servers from the general list are added to the configuration files when creating new clients.

I think u can just change it in the conf file

Also currently it only accepts IPv4 IPs. Would be nice if we can input IPv6 IPs. (and yes i know i can edit config file - i did that)
