> As of today, _OSUtils_ in reef-common module only supports *Linux* in the following functions.
>   * `getPID()`
>   * `kill()`
> This issue improves _OSUtils_ to support *Windows* and *Mac* by implementing the following items.
>   * For `OSUtils.isLinux`, it returns *true* for both Linux and Mac. This enables `getPID()` and `kill()` on Mac.
>   * For `OSUtils.getPID()`, it uses  `powershell -Command wmic process where processid=$pid get parentprocessid` to get pid in Windows.
>   * For `OSUtils.kill()`,  it uses `taskkill /pid` for Windows.
>   * Add OSUtilsTest.java
> Also, this issue fixes the followings.
>   * Add *No-Op* `ActiveContextHandler` to EvaluatorFailureDuringAlarmDriver. `DefaultContextActiveHandler` suicides by closing itself.
>   * `RunnableProcess` cleans up both linux and windows. 
>   * `RunnableProcess` catches `NumberFormatException` from `RunnableProcess.readPID()`.
>   * Bind `PIDStoreStartHandler` to `LocalRuntimeConfiguration`.
