URL: https://github.com/apache/ozone/pull/6611

   ## What changes were proposed in this pull request?
   
   Currently RocksDB compaction is triggered for schema v3 RocksDBs (one DB per 
volume) as part of the volume check. Periodic manual compaction is necessary 
because import of sst files as part of container replication can lead to many 
small sst files in RocksDB.
   
   This operation may slow down the volume check and can have unintended 
consequences if the minimum gap between volume checks is set very high or very 
low. Ideally compaction should be triggered on its own independently controlled 
thread.
