Changes to run multiple machines with "vagrant up --parallel , ..." instead of running multiple vagrant ups in parallel (which was causing serious issues). I.e., implemented a version of acquire_machines specifically for the vagrant driver. Also supporting functions for the parallel case.
Also for halt and delete, i.e., halt_machines and delete_machines.
