[~arvindk12] thanks for you hard work, I will take a look next week.:)

And I think I can help with the CI too. Will run the CI after the first round of review.

> It would be useful for compactionhistory to have:
> a) updated documentation for nodetool [compactionhistory |https://cassandra.apache.org/doc/5.0/cassandra/managing/tools/nodetool/compactionhistory.html] describing the columns *rows_merged* and {*}compaction_properties{*}. This StackOverflow article provides a good descriptions of rows_merged:  [What does rows_merged mean in compactionhistory|https://stackoverflow.com/questions/27566558/what-does-rows-merged-mean-in-compactionhistory]
> b) the compaction strategy used: STCS, LCS, TWCS, UCS and sub-properties. For example, with level, the from-level and to-level could be reported.
> c) also useful would be to make the bytes in and out human readable by default, since there is already an -f option for machine readable output.
