> For fault tolerant, IMRU tasks, MapTaskHost and UpdateTaskHost should implement  IObserver<ICloseEvent>.
When they receive ICloseEvent,  it will verify if the closing event is send from driver based
on the message in the event, then trow IMRUTaskException with a define message to inform the
driver it is closed. 
> The  change should be backward compatible. If the the IMRU tasks are not bound to the
task configuration, the event won't be received.
