Adds Fuel Installation Capability

Adds Fuel Installation Capability

JIRA: N/A

Adds the ability to automatically install and deploy Fuel onto
a remote host.
the hostScripts/fuelInstall.sh script boots the master machine
and uses the fuel iso to install fuel to the machine.
the source/installers/fuel.py then uses the source/api/fuel_api
handler to configure and deploy fuel.
Running:
    Fuel_Installer(domains,networks,libvirt,utility).go()
Will install fuel and deploy Openstack on top of Fuel
assuming the host is properly configured.
