Slurm shell completion

While not directly related to PySlurm, the contribs area of the Slurm source has two convenience helpers:

1. a vim syntax highlighter for batch scripts
2. a bash completion script for scontrol

Have a look at the README page here: https://github.com/SchedMD/slurm/tree/master/contribs/slurm_completion_help

The bash completion script requires the bash-completion package.
