Description

The code related to key and row caches has a bunch of code duplication. It's
moreover a bit scattered, the caches are in SSTableTracker but the scheduled
task to save them are in CFStore. And having the caches in SSTableTracker is
not very logic, for row cache at least, since it does not only concern the
sstables. Proposed patch refactor this to avoid the duplication and put all
the cache handling code in one place.
