The sstables::sstable class has two methods for writing sstables: 1) sstable_writer get_writer(...); 2) future<> write_components(flat_mutation_reader, ...); (1) directly exposes the writer type, so we have to update all users of it (there is not that many) in this same patch. We defer updating users of (2) to a follow-up commits.
