DNS records not updated when renaming a VM

[oakey-b1]

If renaming a VM the dns_name and dns_assignment fields of the port(s) are not updated. Besides that there doesn't seam to be a way to update these records over the dashboard.

I agree, elektra would benefit from this. Again a customer was confused about that behaviour and missing means to change the DNS name.

• [ ] port show does not show the fields mentioned above
• [ ] port update does not allow to change the dns_name
• [ ] server rename could be improved by an optional flag to also change the dns_name, so our customers can decide if the dns_name of the server port should be updated, too or not
