      Description

      While thinking about Sylvain Lebresne's proposal in CASSANDRA-13910, I found myself wondering if we shouldn't also change the read repair behaviour to never work on data that already has been repaired by anti-entropy repair before. Any mismatches on already repaired data could as well be caused by a bug (see CASSANDRA-13004) and writing the data back again will probably do more harm than good.
