The only failing dtest related to compression is
{{jmxmetrics_test.TestJMXMetrics.begin_test}}. As explained in CASSANDRA-10225
the compression assertion is , in my opinion, just wrong. I removed it from the
DTest.

> While reviewing CASSANDRA-10225, I found out that the compression ratio
> returned by the {{StatsMetadata}} for some compressed sstables was - 1
> (NO_COMPRESSION_RATIO).
> After investigation it seems that the wrong compression ratio was serialized
> to disk.
