[08/10] iotests: Add test for BAT entries duplication check

Commit Message

Alexander Ivanov Aug. 17, 2022, 3:53 p.m. UTC

Fill the image with a pattern and write another pattern
in the second cluster. Corrupt the image and check if the pattern
changes. Repair the image and check the patterns on guest
and host sides.
