[slurm-users] slurm reboot node with spank plugin

[Tueur Volvo]

I currently use a plugin node feature like knl
but i don't like use node feature because i must write "feature" in
slurm.conf file

I find this solution rather cumbersome
for example if i want to add kernel 4.4 in my program :
srun -c kernel4.4
i must to updated all slurm.conf file in my cluster, and i can not specify
any option, for example i want to specify compilation option, i must to
create new feature :
kernel4.4_gcc for compile with gcc
kernel4.4_intel_compiler for compile with intel compiler...etc.

i want new solution like spank plugin :
srun --kernel=4.4 --compilation=gcc
