Refactor the printing logic in compaction::formatted_sstables_list out to sstables::to_string(const shared_sstable&, bool include_origin) and operator<<(const shared_sstable) on top of it. So that we can easily print std::vector<shared_sstable> from compaction_manager in the next patch. Signed-off-by: Benny Halevy <bhalevy@scylladb.com>
