Add `boot` node state to node online and offline script. Properly handle `scontrol reboot asap` so Slurm doesn't erroneously online a node after the first NHC call after a reboot. For context, see mej#81 and https://bugs.schedmd.com/show_bug.cgi?id=6391

Sorry, turns out I needed another piece of code. I will force push shortly. |

Sorry, I found some things that need to be reworked. I'll reopen this once I have things figured out. |

scontrol reboot asapwill set the node state toREBOOT+DRAINand reason toReboot ASAP. Then, after boot, and after NHC runs once, Slurm will set the node base state toIDLE. If reason ==Reboot ASAP, Slurm will also clear theDRAINflag. We want NHC to clear theDRAINflag, not Slurm, so delete theReboot ASAPreason by not preserving it below. See https://slurm.schedmd.com/scontrol.html --> reboot.
