> Currently, the memory management monitor's check is disabled when the maxMem is set to
-1. However, the maxMem is also sent to the RM when the NM registers with it ( to define the
max limit of allocate-able resources ). 
> We need an explicit flag to disable monitoring to avoid the problems caused by the overloading
of the max memory value.
