quantity prevents index_reader from reading all index entries of a summary
entry that span more than min_index_interval entries. That can happen after
introduction of size-based sampling, and consequently, sstable will not be
able to return a key which logical position in summary entry is beyond
min_index_interval. It's ok to not use quantity because index_reader will
read all indexes until either next summary entry or end of file is reached.
