KUDU-3406 [compaction] Increase chances of compaction for large number deltas
Current behavior of maintenance manager is based on various factors
before choosing a specific op to be scheduled. There is a case wherein
number of deltas will keep on get accumulated over time. Eventually,
that makes it more difficult for compaction op to process that much
data later on, thereby consuming a lot of memory. In some case,
kernel kills the tablet server because of its high memory usage.
To fix this, weight is given to the rowset compaction op if such
a case arises i.e. accumulation of deltas is huge.
