Rationale for this change

I am trying to help debug a test failure with AQE + DPP and it is hard to understand what is going on just by stepping through code given the recursive nature of planning in AQE. Some logging should help.

Example:

25/05/22 16:36:37.402 ScalaTest-run-running-CometExpressionSuite INFO CometScanRule: 
INPUT: Project [md5(cast(col#23 as binary)) AS md5(col)#34]
+- FileScan parquet spark_catalog.default.test[col#23] Batched: true, DataFilters: [], Format: Parquet, Location: InMemoryFileIndex(1 paths)[file:/home/andy/git/apache/datafusion-comet/spark-warehouse/test], PartitionFilters: [], PushedFilters: [], ReadSchema: struct<col:string>

OUTPUT: Project [md5(cast(col#23 as binary)) AS md5(col)#34]
+- CometScan parquet spark_catalog.default.test[col#23] Batched: true, DataFilters: [], Format: CometParquet, Location: InMemoryFileIndex(1 paths)[file:/home/andy/git/apache/datafusion-comet/spark-warehouse/test], PartitionFilters: [], PushedFilters: [], ReadSchema: struct<col:string>
