d1_cn_index_tool doesn't reindex an pid from a given file
When d1_index_tool reindex an pid from a given file, it will generate a index task by the index generator and save the index task to the db. However, the index generator, there is a new rule that the index task will be ignored if there is no change on the system metadata. So if there is no change on the system metadata, the pid specified in the given file will not be reindexed.
In our Pangaea cases, we need to use different subprocessor to process the object while there are no change on the system metadata. So the d1_index_tool will NOT reindex them.
