#16043 has a number of bad string extractions for translation, in violation of Translating.

1. A few instances where a variable is interpolated before being passed to _(), e.g. _("Reminder: <strong> All #{hosts.size} hosts are selected </strong>")
2. Many instances where the source string uses plural language, but the n_() plural method isn't used, e.g. the line above or __("Select all<b> %s </b> hosts")
3. Trailing whitespace in translated strings, e.g. __("All <b> %d </b> hosts are selected. "). If significant, it should be added after translation.
