Stephanie Miller d4c84944e8 Add options to group_vars to make it match docs
In the README, we state that options will be available in the
plugins/group_vars/all file for the user to uncomment. We missed
adding a few of those options to the file, so I've added them.
I also removed a section of outdated documentation that snuck
back in during a merge.
