This command set/read DNS (Domain Name Server) IP address (primary/secondary) for each socket. If
the user doesn't specify DNS servers by AT+MSDNS, Module will use default DNS from NW. The defined
value(s) will be saved during disconnect PDP context (can be used in next PDP context), but will reset
after power cycle.
