[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.

> 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.
