Nameservers are configured on the ctlplane subnets by the undercloud installer, the nameservers are used early during the deployment, prior to running os-net-config. Remove the default DnsServer's in THT, replacing it with an empty list and use get_attr to get the values for DnsServers for the overcloud from the ctlplane subnet(s). A conditinal is used in puppet/role.role.j2.yaml so that the parameter value is used whenever it is not [] (default) to provide backwards compatibilityi and in case the user want to use different DnsServers for the overcloud and undercloud.
