[feature request]: Allow corefile customization. Specifically for adding a response header for recursive dns.

This will avoid issues because nslookup will otherwise complain and not correctly resolve.

example:

❯ nslookup vps.netmaker_network
;; Got recursion not available from 10.254.66.29, trying next server
Server:		1.1.1.1
Address:	1.1.1.1#53

** server can't find  vps.netmaker_network: NXDOMAIN



❯ nslookup  vps.netmaker_network
Server:		10.254.66.29
Address:	10.254.66.29#53

Name:	 vps.netmaker_network
Address: 10.254.66.28

default Corefile:

. {
    reload 15s
    hosts /root/dnsconfig/netmaker.hosts {
    fallthrough
    }
    forward . 8.8.8.8 8.8.4.4
    log
}

expected Corefile:

. {
    reload 15s
    hosts /root/dnsconfig/netmaker.hosts {
    fallthrough
    }
    forward . 8.8.8.8 8.8.4.4
    log
    header {
       response set ra # set RecursionAvailable flag
    }
}
