Set GPU_DEVICE_ORDINAL environment variable.

Previous logic would try to pick a specific node count and on a
heterogeneous system, this would cause a problem. This change

Added whole_node field to job_resources structure
Enable gang scheduling for jobs with core specialization and other
jobs allocated whole nodes.

i.e. salloc -n32 doesn't request the number of nodes and with the previous
code if this request used 4 nodes and only 1 was left in GrpNodes it
would just run with no issue since we were checking things before we
selected how many nodes it ran on.

Now we check this afterwards so we always check the limits on how many
nodes, cpus and how much memory is to be used.

Fix step allocation when some CPUs are not available due to memory limits.
This happens when one step is active and using memory that blocks the
scheduling of another step on a portion of the CPUs needed. The new step
is now delayed rather than aborting with "Requested node configuration is
not available".

Split a slurmctld's job record "shared" field into "share_res"

gang scheduling of such jobs.
