4851d8461a add proof of concept to create checkpoints 
- HERMIT_CHECKPOINT=x defines the period x (in seconds) to create
  checkpoints
- by starting of an HermitCore application, uhyve checks
  if an checkpoint is avaiable in the subdirectory
  "checkpoint"
- uhyve starts the application from the latest checkpoint
