Adding missing nameserver name to custom A record

[dteplits]

In case custom variables are populated, for example:

DOMAIN=secondary.io
NAME_SERVER_IP=1.2.3.4

Then the zone file should contain the below two records (KubeSecondaryDNS nameserver details as defined in external domain server):

IN NS ns.vm.secondary.io.
ns IN A 1.2.3.4

This PR adds ns prefix inside the A record as shown above.
ns is the default KubeSecondaryDNS nameserver name

The two records eventually will be converted by the DNS engine into this:

vm.secondary.io. IN NS ns.vm.secondary.io.
ns.vm.secondary.io. IN A 1.2.3.4

• NS record has no prefix, therefore @ that comes in the line before (SOA record) should catch here. And be replaced by $ORIGIN value
• A record has ns prefix but no . at the end therefore should be completed with $ORIGIN
