[jira] [Created] (HDDS-5923) Add DBHandle abstraction over ReferenceCountedDB.

Mark Gui created HDDS-5923:
------------------------------

             Summary: Add DBHandle abstraction over ReferenceCountedDB.
                 Key: HDDS-5923
                 URL: https://issues.apache.org/jira/browse/HDDS-5923
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Mark Gui
            Assignee: Mark Gui


For now the dbhandle for rocksdb instance is referenced counted, after merge rocksdb instances, the dbhandles will be pinned in memory until datanode stops.

So we introduce an abstract class DBHandle and it will have 2 sub classes:
 * ReferenceCountedDB
 * RawDB
