   Yes, but we should also consider this case: Public cloud provider offering 
VMs. They have their own PowerDNS environment behind it. Customers can use 
CloudStack to:
   
   - Deploy Virtual Machines
   - Manage Object Storage
   - Managed DNS Zones and Records
   
   A single API to talk to for the customer. They have no idea what DNS 
environment is behind it, they just create a zone and that's it.
   
   Come to think, I think that per provider/driver you should also be able to 
set the NS records. If set, these will be returned by CloudStack as the NS 
records people can use
   
   dns_server_nameservers
   - dns_server_id
   - hostname
   
   > > > the `dns_zone` table stores the information of DNS zones/domains, as 
well as some cloudstack information, for example ownership or dedication. I 
added a column `external_reference` to store the additional information of the 
dns zone on external dns servers.

driver. The driver would return this reference once the zone is created. That's 
what we then use to look up the zone again in that driver. The driver might 
return the zone name, an ID (integer) or a UUID. That's up to the driver.
