> Implement parallel indexing for speeding up oak run indexing command
> Since indexing was single threads, which is slow for large repository. In order to improve the indexing performance we need to implement parallel indexing.
> The work is cover for both lucene and elastic indexing. In order to support parallel indexing, it need to split the big flat file store file ahead, which add a big overhead, but make parallel index possible and much faster.
> Another change together is support the LZ4 compression since which is much faster compare to gzip.
