Pack jobs will never be scheduled in other configurations

The functionality is now fully integrated into the main Slurm code.

burst_buffer/cray plugin modified to work with changes in Cray UP06
   software release.
Specific changes: Cray software now returns an error if a state_in
   or stage_out script is processed that doesn't actually request a
   stage in or out (previously silently ignored).
Also the warning message about tearing down a buffer that is already
   gone changed.

Original test would increase job time limit, which is not possible
  with a normal user

The combination of the first and second digits in the version designate
the major release. The third digit in the version designates the micro release.
minor release word is removed as being confusing and useless.

For a pack job step, set SLURM_NODE_ALIASES appropriately (i.e. ordered)
  for use in a cloud or cloud bursting environment.

Add new function job_alloc_info_ptr() that works like job_alloc_info()
  but takes job pointer.
Set the alias information for all components of a pack job.

Fix for CLANG false positive

Set "timeout" for possibly job launch delay
Also don't log the output of "scontrol show config"

Fix for typo in commit 97a33639
in globals_accounting test function

User-submitted batch scripts cannot be safely escaped. This functionality
will be replaced with a way to retrieve the script directly into a file
for a given jobid.

This also removes the 'script' command from scontrol's interactive
cli mode.

Writes to slurm-<jobid>.sh if no (optional) filename is specified.

Bug 4199.

Resulted in non-operators unable to get their own job script back.

Bug 4199.

Move the check up a bit more where it'll do some good.
