Bug 6680

With schedulerparameters=defer and prolog scripts and/or spank plugins
that take some time, jobs weren't starting within 2 seconds that tests
2.18 and 2.19 expected, causing these tests to fail.

Bug 6670.

IMO, the test as is currently designed is not representative of
an actual rpmbuild against a production released tarball, and thus
should not be relied on. Using --nodeps masks a lot of potential
errors with the spec file.

It has been disabled on Ubuntu systems for months, broken on master
for longer, and thus I am discarding it now.

Bug 4411, 6281.

Change to %pJ identifier while here and merge different partition
priorities into a single log message line.

Bug 6723

Regression from enhancement 4506.

Bug 6680

Bug 6662

Previously the state reason could remain as WAIT_NO_REASON even after
backfill evaluation. This should improve system feedback/responsiveness
user perception.

Bug 6500

Issue was from ade9101e.

The problem was an over simplified if statement which when ran multiple
times would set the start time incorrectly.

Bug 6697

Even if main scheduler doesn't allocate resources for hetjobs, the
queue list should be composed by all types of jobs. Otherwise, lower
priority regular jobs could be allocated resources by main scheduler
while higher priority hetjobs are waiting for a backfill cycle.

Bug 6593.

Bug 6679

Instruct the backfill scheduler to attempt to start a heterogeneous job
as soon as all of its components are determined able to do so.

Bug 5579.

This could probably be extended to give back sockets and cores and
such, but at this moment I really only needed how many threads to deal
with and total cpus.

There are at least two points where this can return a false positive
error message which can be confusing for users.
