[BUG] GPL 2.0 License

[perleino]

What is the bug?
As i understand Opensearch is under Apache 2.0 license. How ever it looks like K-NN is using https://github.com/opensearch-project/k-NN/blob/main/micro-benchmarks/build.gradle#L30 jmh-core that is under GPL 2.0 license: https://github.com/openjdk/jmh/blob/master/LICENSE is this OK from a license perspective ? Should the https://github.com/opensearch-project/k-NN/blob/main/micro-benchmarks be marked as GPL 2.0 ?

@perleino this could have been added by mistake. This package was inspired from: https://github.com/opensearch-project/OpenSearch/blob/main/benchmarks/build.gradle#L54 If jmh is not Apache license, we can remove this module.

Will raise a PR today to remove the module. and later I will see how we can fix it. I see Lucene is also using the same. Let me see how they have implemented this and get away from this GPL thing.
Ref: https://github.com/apache/lucene/tree/main/lucene/benchmark-jmh and I see this too: https://github.com/apache/lucene/blob/main/lucene/benchmark-jmh/src/java/org/apache/lucene/benchmark/jmh/Main.java#L25 so I am little confused why this is a problem with k-NN plugin.

Also, this module is not shipped with Opensearch distribution.

Resolving the GH issue. Since the module is removed.
