   Update stats of table/partition after minor compaction using noscan operation
   
   ### Why are the changes needed?
   <!--
   Please clarify why the changes are needed. For instance,
     1. If you propose a new API, clarify the use case for a new API.
     2. If you fix a bug, you can clarify why it is a bug.
   -->
   Currently, statistics are not updated for minor compaction since minor compaction performs little updates on the statistics (such as number of files in table/partition & total size of the table/partition). It is better to utilize NOSCAN operation  for minor compaction since NOSCAN operations performs faster update of statistics and updates the relevant fields such as number of files & total sizes of the table/partitions.
   
   ### Does this PR introduce _any_ user-facing change?
   <!--
   Note that it means *any* user-facing change including all aspects such as the documentation fix.
   If yes, please clarify the previous behavior and the change this PR proposes - provide the console output, description, screenshot and/or a reproducable example to show the behavior difference if possible.
   If possible, please also clarify if this is a user-facing change compared to the released Hive versions or within the unreleased branches such as master.
   If no, write 'No'.
   -->
   No
   
   ### How was this patch tested?
   <!--
   If tests were added, say they were added here. Please make sure to add some test cases that check the changes thoroughly including negative and positive cases if possible.
   If it was tested in a way different from regular unit tests, please clarify how you tested step by step, ideally copy and paste-able, so that other reviewers can test and check, and descendants can verify in the future.
   If tests were not added, please describe why they were not added and/or why it was difficult to add.
   -->
   Unit tests
