Howard Pritchard d08be74573 SLURM: launch all processes via slurmd
It turns out that the approach of having the HNP do the
fork/exec of MPI ranks on the head node in a SLURM environment
introduces problems when users/sysadmins want to use the SLURM
scancl tool or sbatch --signal option to signal a job.

This commit disables use of the HNP fork/exec procedure when
a job is launched into a SLURM controlled allocation.

update NEWS with a blurb about new ras framework mca parameter.
