Adds deploy.sh for Foreman/QuickStack
PATCHSET2: Fixes whitespace issue and adds default_gw substitution in
ksgen settings file

Creates a Vagrant VM provisioned with VirtualBox.  The Vagrantfile
config is modified at runtime with dynamic support for baremetal network
setup.  IP addresses and other network info are gathered at runtime and
passed to the .yaml file which is fed into Khaleesi to install
Foreman/QuickStack and provision hosts.  For the script usage it is
recommended to include the following inside of the yaml file set:
 - mac_address: "01:23:45:67:89:AB" <-Mac Address of admin interface
 - bmc_ip: 10.4.17.2
 - bmc_mac: "01:23:45:67:88:AB"
 - bmc_user: root
 - bmc_pass: root
