   a) remove mergeIndex property and event listener, add mergeIndex as a part
of loading/compaction transaction.
   b) if the merging index failed, loading/compaction should fail directly.
   c) keep merge_index command and mark it deprecated.
      for a new table, maybe it will do nothing.
      for an old table, maybe we need to tolerate the probable query issue
(not found index files).
      It could be a deprecated feature in the future.
   b). At the end of loading,  retrying to finish index merging or
tablestatus update is a good suggestion.
