SAMZA-1498: Support arbitrary system clock timer in operators This patch adds the capability to register arbitrary timers for both high-level and low-level api. For high-level, InitableFunction will pass the TimerRegistry to user through the new OpContext, and user will implement the TimerFunction to get timer notifications. For low-level api, user can register timer in the TaskContext, and then implements the TimerCallback for specific timer actions.
