[FLINK-2848] [test] Apply JMH on MutableHashTablePerformanceBenchmark…
JMH is a Java harness for building, running, and analysing
nano/micro/milli/macro benchmarks.Use JMH to replace the old micro benchmarks
method in order to get much more accurate results.Modify the
`MutableHashTablePerformanceBenchmark` class and move it to `flink-benchmark`
module.

> Priority: Minor
>
> There are many flink internal micro benchmarks in different modules, which
> are coarse measured(by System.currentNanoTime()...), and with no warmup or
> multi iteration test. This is an umbrella JIRA to refactor these micro
> benchmarks and move to flink-benchmark module for central management.
