> Assuming there are no bugs in the REEF/IMRU system, we would like to catch all known
exceptions and converted them into the categories of IMRUTaskAppException(any exceptions caused
by user code, is not recoverable) IMRUTaskGroupCommunicationException(exceptions caused by
group communications, is recoverable) and IMRUTaskSystemException (any other system errors
or transit errors and can be recover).
> As there might have new exceptions, we will leave the default as a recoverable exception.

> Most of the code is already implemented in REEF-1251. We need to do a refactor/clean
up.
