Have 14.04 LTS HWE upgrade messages translatable well in time before they are needed

In the case of 12.04 LTS the HWE upgrade messages became available only last week, meaning that no-one is getting the messages in their own non-English languages at the moment. Even if the translations would now be done in Launchpad, LTS langpack updates are often quite rare.

For 14.04 LTS, it'd be great to add the same update-manager messages already now for the next SRU upload (something that takes its own time as well), so that they'd become available for translation as soon as possible at: https://translations.launchpad.net/ubuntu/trusty/+source/update-manager Then the messages could be translated, and included in some future 14.04 LTS langpack update well in time before 16.04 LTS comes out and they are actually shown to the users.
