    Libvirt: make boot dev a list in GuestConfig

    In order to make boot order more flexible based on the block device
    mapping passed, we need to customize the domain xml presented to
    libvirt, by specifying more than one boot element. For more info see
    http://libvirt.org/formatdomain.html#elementsOSBIOS. Currently the boot
    element is hard coded to "hd" by the libvirt driver.

    This patch makes it possible to specify more than one boot element that
    will give us more flexibility.
