Title: nova-agent should replace the Slice or Image ID rather than append

/etc/conf.d/nova-agent does not appear to be in practice an audit trail of all the instance ID assignments for a changing guest instance. Instead, /etc/conf.d/nova-agent should record only the current UUID and be a well-formed one line document. Currently, well-formed UUIDs are either FirstGen slice numbers or NextGen instance IDs.
