[slurm-users] ignore gpu resources to scheduled the cpu based jobs

[navin srivastava]

Thanks Renfro.

Yes we have both types of nodes with gpu and nongpu.
Also some users job require gpu and some applications use only CPU.

So the issue happens when user priority is high and waiting for gpu
resources which is not available and the job with lower priority is waiting
even though enough CPU is available which need only CPU resources.

When I hold gpu  jobs the cpu  jobs will go through.
