…apache#7771) ### Motivation Adding a subdirectory associated with current time willmake it easier to process HDFS files in batch. For example, user can create multiple running sink instances with `yyyy-MM-dd-hh` pattern. Then stop all instances at next hour. Eventually, files of the subdirectory will contain all messages consumed during this hour. ### Modifications - Add a `subdirectoryPattern` field to `HdfsSinkConfig` - Update some simple tests for `HdfsSinkConfig` - Update the doc of HDFS2 sink ### Documentation - Does this pull request introduce a new feature? (yes) - If yes, how is the feature documented? (docs)

Motivation
Adding a subdirectory associated with current time willmake it easier to process HDFS files in batch.
For example, user can create multiple running sink instances with
yyyy-MM-dd-hhpattern. Then stop all instances at next hour. Eventually, files of the subdirectory will contain all messages consumed during this hour.Modifications
