DnsServers using get_attr

Browse Source 
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.
