Currently we are missing cleanup routine for case when power failure interrupts creating snapshot. This patch add such routine. For the case where we find blob with a parent snapshot ID matching newly created snapshot we can finish whole process during recovery by processing forward with setting snpashot as read only, removing xattr and syncing. We should remove snapshot only if there is no blob with parent pointing at snapshot.
