update_engine: Add new rollback policy values

The new values are:
- RollbackAndRestoreIfPossible: always roll back, but try to save and
  restore data if possible. This is rollback_allowed=true.
- RollbackWithRestoreOnly: only roll back if it's possible to save and
  restore data. This is rollback_allowed=false until data save and
  restore is implemented.
