[one-users] Leftover checkpoint files after resume

Yes you can removed them. Once the VM is running again the file is not used
anymore. In case you need to save the VM again a new checkpoint is generated

At least this should be configurable in the driver file. Currently when you
save a VM we move previous checkpoint files to checkpoint.<epoch> in case
you need them if something goes wrong. See [1], I've filled an issue to
take a look at this [2]
