[java] Improve space complexity about prune hash partitions for in-list
predicate
Pruning hash partitions for in-list predicate at java-client, the logic
codes has a high space complexity, and it may cause java-client out
of memory.
This patch fixes the problem and provide a recursive algorithm, that
uses a method like 'deep first search' to pick all combinations and
try to release PartialRow objects ASAP.
