      Description

      FileTablespace::commitOutputData has some problems as following:

      First, it is too long and complexed because it handles various cases in a single method. We need to refactor this method into several small and well-defined methods.

      Second, FileSystem::listStatus is widely used while committing output data. It especially causes a lot of overhead to list partitioned directories in S3. Also it occurs in HDFS too with large partitioned tables. We need to minimize its usage.
