[Openstack-i18n] "sell puppies" and "sold puppies" in Horizon

Hello, all If you are translating Horizon today, you may notice two new strings appeared in "Juno - Horizon translations": "sell puppies" and "sold puppies". Don't worry about the translations of these two strings. They are just for testing. You could translate them as usual or just copy the English version there. Best regards Ying Chun Guo (Daisy)
