I'd like you to reexamine a change. Please visit

to look at the new patch set (#6).
Change subject: [KUDU-3367][compaction] Fix delta file with full of delete op
can not be schedule to compact

[KUDU-3367][compaction] Fix delta file with full of delete op can not be
schedule to compact
If we get a REDO delta with full of delete op, wich means there is no update op
in the file. The current compact algorithm will not schedule the file do
compact.
If such files exist, after accumulating for a period of time, it will greatly
affect our scan speed. However, processing such files every time compact reduces
compact's performance.
So I added a flag FLAGS_check_delete_op_for_compact_ratio to solve this
situation.
Major compact will deal with delta file with full of delete op by the
probability
specified in FLAGS_check_delete_op_for_compact_ratio value.
