Bug 5711

This will be re-reverted in 19.05 with other code changes we didn't feel
comfortable dealing with in 18.08.

Bug 5702

The select_p_job_test() function is called once for the cons_tres
plugin with all available nodes rather than multiple times based
upon incrementally adding nodes based upon weight. This change
modifies the _eval_nodes_busy() and _eval_nodes_spread() functions
to use low node weights first and incrementally add higher weight
nodes as needed

Cores can be removed from availability in order to co-allocate CPUs and GPUs.
This change updates the available CPU count on a node when cores are removed
from availability by clearing bits in the core_bitmap.

Log not just the job ID and node name, but core_bitmap
and sockets to be avoided.

"Rebood" changed to "Reboot"

This throws 0c3133a2 out, as that'd already been handled here previously.
(And thus we do not add a separate NEWS entry for 18.08.1 on this issue.)

The backup slurmctld can end up without an agent thread if
read_slurm_conf() takes too long to complete. Forcing the agent_init()
here again ensures it is restarted if not currently running.

This was fixed upstream in c1a537db.

Bug 5633.

"Generalized Hypercube - A Topology Plugin" was accidentally given
a 50 minute slot instead of 30 minutes as it should have been. Carry
the fix forward through the schedule, and cede the extra time to Google.

Bug found by clang

Slight hit from heap based strings instead of stack, but worth
it to remove sprintf() call in lightly-used debug path.

Rather than reworking to remove the sprintf(), just remove this now.
