ndots creates overhead as every pod creates 5 concurrent connections that are forwarded to sky dns. Under some circumstances dnsmasq may prevent forwarding traffic with "Maximum number of concurrent DNS queries reached" in the logs. This patch allows to configure the number of concurrent forwarded DNS queries "dns-forward-max" as well as "cache-size" leaving the default values as they were before.
