made the vagrant bootstrap script non-interactive. This fixes a problem during Vagrant set up of Ubuntu where it gets stuck on installing grub-2, because there is no human input. Without this fix, one needs to ctrl-c out of the vagrant ubuntu install, do 'vagrant ssh' into the vm, do some dpkg stuff selecting the right options for grub-2, before it succeeds. This is discouraging for new comers to vagrant and linux. (#694)
