Vagrantfile: Add openSUSE support

In preparation for adding openSUSE support, we extend the Vagrantfile
to support openSUSE Leap 42.2/42.3 and extend the btrfs filesystem to the
requested size. The parted version in Leap 42.2/42.3 does not allow online
partition size alternations so we delete and re-create the partition
using fdisk.
