I'm attacking in order
to familiarise myself with the code.

I've added a repairedAt field to SSTableMetadata as suggested, and to its
non-legacy serialised form. Now I'm trying to figure out where the field
should be used.
My guess is, that if I change getScanners(sstables, range) in Abstract- and
LeveledCompactionStrategy to not include SSTables that have repairedAt
stamps in their metadata, in the returned list of scanners, then that would
solve the part about not generating MerkleTrees for already repaired
sstables. Then the next step will be writing repairedAt metadata for tables
that do get repaired.

Is this thinking correct?
