Useful for batch jobs (in Prolog or the script) if powering down idle nodes.

    wait for all allocated nodes to power up before proceeding. Salloc will
    log the delay with the messages "Waiting for nodes to boot" and "Nodes are
    ready for use". Srun will generate the same messages only if the --verbose
    option is used.

sview - there is now a .slurm/sviewrc created when runnning sview.  Defaults are put in there as to how sview looks when first launched.  You can set these by Ctrl-S or Options->Set Default Settings.

Fixed a couple of problems for NO_CONF_HASH too (bits were 0x12, changed
to 0x20, added documentation to slurm.conf man page, and add logging for
scontrol show config).

put in a working .conf so we can tell the difference between what is in the .rc and what has changed

    problem.

  preserve config gres string so we can validate node registration values
  against original config rather than revised config with fast schedule=0
