> 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.
