sdong db320b1b82 DB to only flush the column family with the largest memtable while option.db_write_buffer_size is hit 
Summary: When option.db_write_buffer_size is hit, we currently flush all column families. Move to flush the column family with the largest active memt table instead. In this way, we can avoid too many small files in some cases.

Test Plan: Modify test DBTest.SharedWriteBuffer to work with the updated behavior
