    allow disabling file injection completely
    
    With the libvirt_injection_partition config set to -2,
    file injection is avoided completely.
    
    This can be required if you want to make user specified files
    available from the metadata server (and config drive is not enabled),
    then you would want to avoid injection completely for performance reasons,
    but also to avoid boot failure if the injection itself failed.
