Hi, [~pauloricardomg] and [~yukim]. 
Sorry I couldn't reply earlier because I have been with exams during these weeks and thanks
for reviewing the proposal. I agree that it's better to have first a basic sstabledowngrader
than jumping directly to the framework, I have modified it according to your suggestions.
I'll make another change if it's needed.
Till now I have been looking for inspection tools, I guess I don't have any problems related
with the usage. I'll keep on looking for sstablescrubber tool.
In addition, do you mean with double cycle support that our sstabledowngrader should work
correctly with a flow like "ma" -> "ka" -> "la"?

> As mentioned in other places such as CASSANDRA-8047 and in the wild, sometimes you need
to go back.  A downgrade sstables utility would be nice for a lot of reasons and I don't know
that supporting going back to the previous major version format would be too much code since
we already support reading the previous version.
