* Update docs/submodules/pharos from branch 'master'
  - Merge "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.
