Dhruba Borthakur 4012ca1c7b Added a parameter to limit the maximum space amplification for universal compaction. ... Summary: Added a new field called max_size_amplification_ratio in the CompactionOptionsUniversal structure. This determines the maximum percentage overhead of space amplification. The size amplification is defined to be the ratio between the size of the oldest file to the sum of the sizes of all other files. If the size amplification exceeds the specified value, then min_merge_width and max_merge_width are ignored and a full compaction of all files is done. A value of 10 means that the size a database that stores 100 bytes of user data could occupy 110 bytes of physical storage. Test Plan: Unit test DBTest.UniversalCompactionSpaceAmplification added.
