Modify AuthInfo configuration parameter to accept credential lifetime

Add node state string suffix of "$" to identify nodes in maintenance
reservation or scheduled for reboot. This applies to scontrol, sinfo,
and sview commands.
Enable scontrol to clear a nodes's scheduled reboot by setting its state
to "RESUME".

Disable a partition test if JobSubmitPlugins=all_partitions

When nodes scheduled for reboot, set state to DOWN rather than FUTURE so
they are still visible to sinfo. State set to IDLE after reboot completes.

Srun executable names beginning with "." will be resolved based upon the
working directory and path on the compute node rather than the submit node.

suggest parentheses around assignment used as truth value.

The code tries to load libslurm.so even if precedent dlopen calls
succeeded. The code is structured so that we have to "return;" as
soon as a dlopen succeeds.

This corrects logic introduced yesterday in commit
6f89dc9d which introduced a double
free of step records, at least on job requeue.

Describe restrictions on specific job and step record purging functions
with respect to "cleaning" flag used for Node Health Check on Cray systems.

Always call select_g_step_finish() when terminating a job step,
even if the job is also being terminated. This is needed for Cray
systems.
bug 1012

When a job is requeued, call deallocate_nodes() with a job state
if COMPLETING. Previously it was called with a state of JOB_REQUEUE,
which could be problematic for step complete function calls (which
I am working on fixing now).

Remove some duplicate code. No change in functionality.

When a job record is purged, simply purge the step list rather than possibly invoking a node health check on Cray systems.

No checking or other operations are performed on this list, just a purge.
