URL: https://github.com/apache/incubator-doris/issues/4821


   **Is your feature request related to a problem? Please describe.**
   In the Running Profile, the statistical values of the OLAP_SCAN_NODE node 
are too many, including the statistical values of OlapScanner and 
SegmentIterator.
   This leads to poor readability of the Running Profile and contains multiple 
meaningless statistical values.
   
   
   **Describe the solution you'd like**
   I suggest dividing the OLAP_SCAN_NODE profile into three layers: 
ʻOLAP_SCAN_NODE`, ʻOlapScanner`, and `SegmentIterator` according to the calling 
relationship, and delete meaningless statistical values.
