starts and then a minor typo fix

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".

No change in logic, just rename a variable for better clarity.

This reverts commit 3464295e.

than configured, just log it using debug message type

The previous changes in commit bc3d8828
failed to address some accounting issues addressed here.

If a job is explicitly suspended, its priority is set to zero.
This resets the priority when requeued and also documents that
if the job is requeued (e.g. due to a node failure), then it
is placed in a held state.
