Fix the memory allocation bug which allowed for users to request any amount of memory from slurm. Slurm may reject their request, but the filter placed on VCell was not stoping these requests to begin with. Fixed it for the simulation state machine, but SlurmProxy still requires some changes.

It was failing due to the job prefix not being what is expected within the Zombie killer function. This was resolved by using a function that retrieves the expected job prefix dynamically instead of statically.
