Add ability to prevent suspension of some count of nodes in a specified
    range using the SuspendExcNodes configuration parameter.

e.g. scontrol show jobs
Non-formatted tres strings (e.g. tres_alloc_str * SIMPLE) strings need

Will set the DISPLAY variable in the adopted process automatically
if the job has an active forwarding session.

Returns display for X11 forwarding, or zero if forwarding
is not setup.

Bug 4120

srun --x11 will default to requesting X11 forwarding from
all nodes on a new allocation.

srun --x11 is ignored within an existing job allocation,
as the X11 forwarding must be setup by the prolog which
will have already run.

salloc --x11 will default to requesting X11 forwarding from
all nodes.

sbatch --x11 will default to requesting X11 forwarding from
the batch host only.

The pack_node_list may not be ordered across multiple components, which can
  cause problems for some MPI implementations. Put the pack_node_list records
  in alphabetic order and reorder pack_task_cnts pack_tids to match
