Subject: dns forwarding: T2486: add conf nodes 'addnta', 'recursion-desired',
 migrator

Add new nodes for 'service dns forwarding domain':
'addnta': adds addNTA to lua-config-file
'recursion-desired': sets '+' before the zone in forward-zones-file

The migrator sets both options for all configured domains. This is
usually the desired config.
