[neutron][ovn] domain-search dhcp option per network/subnet level

Greetings to all! In my openstack setup (vanilla ubuntu 22.04 Zed release + OVN networking ) I try to find a way to setup a scheme where my instances should get dhcp search domain option on network/subnet level.

For example - when I create network/subnet, I want to tell neutron, that all created ports in that network/subnet must receive my dhcp search-domain option

Any help advices will appreciated. Thank you!
