"""This test checks the data integrity after creating and restoring
snapshots. The procedure is as follows:
1) Create an instance with ephemeral disk
2) Create a volume, attach it to the instance and create a filesystem
on it and mount it
3) Mount the volume, create a file and write data into it, Unmount it
4) create snapshot
5) repeat 3 and 4 two more times (simply creating 3 snapshots)
Now create volume from the snapshots one by one, attach it to the
instance and check the number of files and file content at each
point when snapshot was created.
