Use dedicated option NeutronDnsDomain instead of ExtraConfig
Use dedicated option NeutronDnsDomain instead of ExtraConfig

To configure dns_domain in the Neutron config, there is dedicated
option called NeutronDnsDomain in the Tripleo-Heat-Templates so there
is no need to use ExtraConfig for that.
It seems also that for some reason, using ExtraConfig for that don't
works well in OSP-17 (see related BZ) so that change should fix it.
