[REEF-1554] Fix .NET Core compatibility issues in REEF.Wake

This change addressed the issue by
  * Replacing System.Timers.Timer in TimerStage class with System.Threading.Timer
  * Adding timer period and initialDelay parameter verification since interface
    is 64 bit and .NET Core class only supports 32 bit.
  * Adding unit tests to verify TimerStage behavior.
