The i18n team has decided not to translate the logs because it seems like it not very useful; operators prefer to have them in English so that they can search for those strings on the internet. Partially fix on nova/conductor, nova/console, nova/consoleauth, nova/db and nova/image other paths will be fixed on next commits Change-Id: I132f60cb4743f85c96ec5231d6f860cfb0815758
