[Java][License] GPLv2 license of jmh benchmark tool conflict with ASF's license policy

Is your feature request related to a problem? Please describe.

fury-benchmark and perftests use https://github.com/openjdk/jmh for benchmark tests.

JMH is licensed under GPLv2, which doesn't comply with ASF's license policy when releasing source/binary packages, even though Fury just refers to some "org.openjdk.jmh."

Describe the solution you'd like

According to apache license doc: https://www.apache.org/legal/resolved.html#optional

If we make jmh dependency as optional, we can use such dependencies.
