This change abstracts reading from on-disk data sources behind a single reader which is then composed with memtable readers. This change also abstracts all data sources behind a single reader obtained via column_family::make_reader(). That reader is then used by algorithms like column_family::for_all_partitions() or column_family::query(). Having those abstractions will make it easier to add row cache, because it will be encapsulated in a single place.
