Ignore node status booted by Slurm

[mehdid]

Changing state of booting nodes when botted by Slurm energy saving feature can mess up with Slurm node state power flags. To avoid this issue, the patch below makes NHC ignore node with state "idle#" in order to avoid offlining them.

A tested patch is available at: https://github.com/edf-hpc/warewulf-nhc/blob/master/debian/patches/0003-ignore-node-status-booted-by-slurm.patch

Would it maybe make sense to ignore states matching *[\*\#@] in node-mark-offline?

As '#' denotes all nodes being powered up, I think your suggestion makes sense and covers all possible states, including idle#. But so far, we've only got the issue with idle#.

I'm going to address this in at least 2, and most likely 3, different ways among the upcoming release versions. In order to avoid duplicating lots of stuff, I'm going to to close this issue in favor of #84 and use that to track the conversation overall. But FWIW, I plan to address this in all 3 versions (1.4.3, 1.4.4, and 1.5)!
