All current unit tests for scrub in validate mode generate random SSTables on the fly. Add some more tests with frozen Cassandra SSTables from the source tree to verify compatibility with Cassandra. Use some of the existing 3.x Cassandra SSTables to test the valid case, and use the same schema to generate some corrupted SSTables for the invalid case. Overall, the new tests cover the following scenarios: * valid compressed/uncompressed * compressed/uncompressed with invalid checksums * compressed/uncompressed with invalid digest For the compressed SSTable with invalid checksums, a small chunk length was used (4KiB) to have more chunks with less disk space. For uncompressed SSTables the chunk length is not configurable. Finally, since the SSTables live in the source tree, the quarantine mechanism was disabled.
