Have mvnd run for some popular Maven projects to show performance improvements

The project looks promising and it would make a good argument to know the performance improvement of running the builds with mvnd and without. That allows the developers to quantify the performance improvements, and take a much better call.

Projects for benchmarking
- [Apache Spark][1]
- [Apache Flink][2]
- [Guava][3]
- [Apache Dubbo][4]
- [Netty][5]
- More....

[1]: https://github.com/apache/spark
[2]: https://github.com/apache/flink
[3]: https://github.com/google/guava
[4]: https://github.com/apache/dubbo
[5]: https://github.com/netty/netty

Start by reviewing the listed Apache Spark, Apache Flink, Guava, Apache Dubbo, and Netty repositories and defining comparable builds with mvnd and Maven. Done means publishing repeatable benchmark results that quantify the performance difference across the selected projects.
