Add preserve_ephemeral option to rebuild

The preserve_ephemeral option for rebuild will preserve the content of
the ephemeral partition, making stateful golden image based
deployments possible even when clouds haven't deployed Cinder, or the
hypervisor doesn't support Cinder (e.g. BareMetal / Ironic).
