> Currently in ActiveContextManager, we have a property exposed AreAllContextsReceived. Whe nreceiving IActiveContext event, IMRU driver can pull the value of this property to decide if it is ready to submit tasks. 
> Instead, we can register an observer to ActiveContextManager. After receiving the last active context, it will notify the observer for submitting tasks.
