---------------------------------------------------------------------------

Hi [~mck], do we have somewhere documented what exact Cassandra versions were 
used to generate each SSTable file? 
Probably we can render a text file with Cassandra version/commit id used to 
generate the files in testGenerateSstables() to document the files origin.
For .keep files it would be helpful to add a comment as a content with a 
clarification why do we have the directories empty for some of format versions 
(it does not look obvious sometimes, for example why there is an empty 
directory in a sequence of non-empty versions: legacy_me_tuple is not empty, 
legacy_na_tuple is empty, legacy_nb_tuple is not empty)
