Default nameservers per registrar
It would be useful to have the possibility to configure different default nameservers for every registrar.
- if the domain is ordered together with hosting service and hosting server has default nameservers configured, take hosting server's default nameservers;
- otherwise, if the domain is ordered alone and the registrar has default nameservers configured, take registrar's nameservers (enabling DNS management to function out of the box);
- otherwise take WHMCS-wide default nameservers.
At order time, users should be able to make a simple selection of nameservers group (a select box: Default Hosting, Default Parking, Custom Nameservers), and get the appropriate NS fields populated automatically based on selected TLD and whether the order contains hosting or not.
