HBCK2 replication command is incompatible with 2.0.x

Details

    Description

      HBCK2 does not have a valid version check for `replication` command on 2.0 releases.

      This command relies on ReplicationQueueStorage and ReplicationStorageFactory classes which were added in 2.1.0 so running HBCK2 replication on a 2.0 cluster causes runtime error.
