Summary by GPT-4

The changes in this commit include:

1. In NetworkManager.scala, the log message for "received nodes for network init" has been moved after the log message for "received partition topology". This change makes the log messages appear in a more logical order.

2. A new log message has been added in parseExecutorPartitionList function to show the partitions received by each executor.

3. In StreamingPartitionTask.scala, some log messages have been changed from info level to debug level, as they might be too verbose for normal operation. These messages include "Inserting rows into training Dataset" and "Pushing dense/sparse rows".

4. Some unnecessary log messages have been removed, such as "Adjusting initial scores", "Pushing sparse rows", and "LightGBM pushed startIndex in partition".

Overall, these changes improve the readability and usefulness of the log messages generated by LightGBM during training.
