sched/backfill: Correct job start time estimate with advanced reservations.
Under some conditions, the job start time would be set to the end time
of an advanced reservation that may have nothing to do with that job's
resource requirements.

Log more backfill scheduling actions including where/when jobs will run even if they can not start until long in the future

If we don't it could get messed up on a reconfig.

When they fail, only the first line of the test description in README
is output, so we want it to capture the nature of the failure on
that first line.

Logic used to identify cores which are usable with each GRES weas incorrect.
bug 905

QOS had a GrpNodes set.

Fix for core-based advanced reservations where the distribution of cores
across nodes is not even. Failing test case:
system has 10 nodes, 1 of which is fully occupied
create reservation with 9 nodes and 10 cores
always would fail with "busy nodes" error
