-----------------------------------
Reviewer: Jason Brown
> Add build support for JMH microbenchmarks

> Making performance changes to C* often requires verification by stress or
> cstar.datastax.com. Other changes can be verified with a microbenchmark tool
> like JMH. As a developer, maintaining a separate project to run these is a
> pain.
> This patch adds support to run microbenchmarks as a separate ant target.
> Also adds a sample showing some of the benchmark annotation options.
> {code}
> ant microbench -Dbenchmark.name=Sample
> ...
> [java] Benchmark (duplicateLookback) (pageSize)
> (randomRatio) (randomRunLength) (uniquePages) Mode Samples Score
> Error Units
> [java] o.a.c.t.m.Sample.lz4 4..128 65536

> ops/ms
> {code}
> If you skip the benchmark.name property it will run all microbenchmarks
> (under the microbenchmark package namespace)
> One annoying thing about this patch is it now adds this error on build which
> is an annoying but harmless warning
> {code}
> [javac] warning: Supported source version 'RELEASE_6' from annotation
