Outstanding PRs for 1.2.0-RC2

There was a flurry of PR activity today around host groups and
taxonomies, but I haven't been following the conversations. Could
people please get these merged early tomorrow morning if they need to
make RC2? Else let me know if you're happy with the current state

The other two PRs I intend to merge before then are:
https://github.com/theforeman/foreman/pull/694 (templates refresh)

& possibly https://github.com/theforeman/foreman/pull/697
