SLURM module can't handle multi-cluster setup

[hv15]

SLURM allows multiple clusters to be defined and used by clients to submit jobs to, with most all SLURM commands supporting the --clusters=... or -M ... flag, or in some cases through the SLURM_CLUSTERS=... environment variable for selecting which cluster to interact with.

PDSH seems not to support either option: no flag is defined for passing in cluster(s) specification, nor is the SLURM_CLUSTERS env variable read.

Thanks! The pdsh Slurm plugin was written before Slurm multi cluster support, and unfortunately this was never added. Happy to accept a PR if you want to give the implementation a shot! I'm not sure I have any way of testing it at this point.
