Akanksha Mahajan 4cd16d65ae Add new option num_file_reads_for_auto_readahead in BlockBasedTableOptions (#10556)
Summary:
RocksDB does auto-readahead for iterators on noticing more
than two reads for a table file if user doesn't provide readahead_size and reads are sequential.
A new option num_file_reads_for_auto_readahead is added which can be
configured and indicates after how many sequential reads prefetching should
be start.
