Adds clean script for Foreman/QuickStack Install Server

Script should be executed on the jumphost baremetal to ensure the clean state of a POD.
clean.sh will do the following:
 - IPMI power off all the nodes
 - Vagrant destroy the VM
 - Remove VirtualBox Package
 - Remove VirtualBox kernel modules from the host
