Subject: [PATCH] enhancement(slurmctld): enforce job level memory

These changes introduce default values for SelectTypeParameters
and MemSpecLimit.

`SelectTypeParameters=CR_CPU_Memory` to enable memory allocation
enforcement.

`MemSpecLimit=1024` to ensure systems always have 1G available
memory that jobs cannot consume.
