---------------------------------------------------------------------
As far as i can see, reseting levels was not done when moving from STCS to LCS
or when changing compaction options before this, the json file was left behind,
meaning, for example that a change to max sstable size might leave data with a
too high level etc.
anyway, v7 resets levels when changing to LCS (or when updating compaction
strategy options).

> Now that we have a metadata component it would be better to keep sstable
> level there, than in a separate manifest. With information per-sstable we
> don't need to do a full re-level if there is corruption.
