[Openstack-i18n] designate-dashboard missing template strings

Hi, Strings in templates of designate-dashboard are not extracted now. https://bugs.launchpad.net/designate/+bug/1561203 and I proposed a fix at https://review.openstack.org/#/c/296807/ Questions for the team is whether we should have this in mitaka? We are in the hard string freeze after RC1 phase. This change violates the string freeze. However this change only add new strings and allows translators to translate strings which cannot be translated now. This add 18 fuzzy translations, 8 untranslated messages. I think it is acceptable from i18n view. Thought? Akihiro
