tests: Add new scrubbing tests
Add new tests for checking objects scrubbing with the docker environment:
- run storage scrubbing on directories while contents were intentionally removed from storage and check missing contents are reported
- run journal scrubbing after having intentionally added a corrupted snapshot in kafka topic and check it is detected
- run object storage scrubbing on a hacked object storage and check corrupted and missing contents are detected
