Description of problem:
Designate is configured and running, a zone is set on the project.
We create a Network with dns_domain set with the zone name (for example: test.prod.iaas.xxx.fr.).
When we create a new instance (myvm) on a network that has the entry dns_domain set.
The port created for the instance does not contain dns_assignment with the expected values (myvm.test.prod.iaas.xxx.fr.).
When we attached a FIP (that does not contain dns_domain value), the FIP normaly will have the dns_assignment attached to it and the DNS entry on designate myvm.test.prod.iaas.xxx.fr will contain the IP of the FIP.

Version-Release number of selected component (if applicable):
[rhosp-release] Red Hat OpenStack Platform release 17.1.1 (Wallaby)
[os-release] Red Hat Enterprise Linux 9.2 (Plow) 9.2 (Plow)

How reproducible:
Every time the instance or the port is attached to the floating IP no record is published

Steps to Reproduce:
0. (overcloud) [stack@underadmin ~]$ openstack network show dnstest-net

2. (overcloud) [stack@underadmin ~]$ openstack floating ip create 1f893c50-8533-49f5-b946-2b6585585f4a --port testgsRH5
3. (overcloud) [stack@underadmin ~]$ openstack recordset list test.prod.iaas.xxx.fr. |grep -i testgsrh

Actual results:
No recordset on dns

Expected results:
testgsRH5.test.prod.iaas.xxx.fr. should be present on dns
