Description

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`.
