Report correct partition associated with a step if the job is submitted to
multiple partitions. Previously all of the partitions that the job could
run in would be reported for the step.

Add more detail to sched/backfill logging

If MinJobAge is configured too low, then job records can be purged
before these tests issue the job requeue test, resulting in their
failure

Without this, the record of gres allocated to steps will remain
allocated and not be available to job steps after being requeued.

sched/backfill - If job started with infinite time limit, set its end_time
one year in the future. Previous logic would based it upon INFINITE and
produce an overflow of the uint32_t time.

Report correct CPU count allocated to job when allocated whole node even if
not using all CPUs.
bug 909

Rather than relying upon the default shared value being (uint16_t)NO_VAL;

Don't log the job's incoming nice value is NO_VAL - NICE_OFFSET

A function was added in commit 7cae0abb
that was essentially identical to a previously existant function.
The redundant function has been removed.

Fix bug which could report to squeue the wrong partition for a running job
that is submitted to multiple partitions.
