Disable a test for select/linear and only one node

Disable test with select/linear and only one node

Bug 1495

This implements the same logic changes to the SGI hypercube and
  dragonfly network logic was was done to the regular and topology
  portions of the code in version 14.11, commit
  58623ec7

Conflicts:

It was deplicated years ago. The option will still work though.

Correct count of CPUs allocated to job on system with hyperthreads.
The bug was introduced in commit a6d3074d
On a system with hyperthreads:
srun -n1 --ntasks-per-core=1 hostname
you would get:
slurmctld: error: job_update_cpu_cnt: cpu_cnt underflow on job_id 67072

preempt/job_prio plugin: Implement the concept of Warm-up Time here. Use
the QoS GraceTime as the amount of time to wait before preempting.
Basically, skip preemption if your time is not up.

	src/slurmctld/acct_policy.c

-W/--wait is only supported by srun and should not show
up in the usage string of sbatch or salloc.

These fields are not currently in use, but have been added for
  future use.

a job runs past it's time limit.

Bug 1705

Don't clear a reservations power cap in update reqeust comes from older
  version of scontrol
Fix two memory leaks due to missing list_iterator_destroy() functions
Some minor format changes

In "if (use_cluster_list != arch_cond->job_cond->cluster_list)"
"arch_cond->job_cond" could be NULL

Change error message contents from "PowerCap" to "PowerParameters"
Fix scontrol parsing for update argument so "partition" requires at
  least two characters ("pa") as does "powercapping" ("po")
Prevent use of unitialized variable "rc" in scontrol_update_layout()
Remove dead (unused) variable store in "tag_len"

Use PowerParameters instead for greater flexibility

an error in powercap logic
a bug in reservation
a bug in licenses
forgotten declaration of functions
forgotten include
error in format
fix incompatible plugin version for power layout
correct target for wrong protocol version on pack/unpack functions

The previous power reservation check, replicated from job_test_lic_resv
is not well protected against consecutives reservations for which
reserved watts (or licenses count) can not be added directly.
Thus, if the job overlaps multiple non-overlapping reservations,
it will be prevented to use more watts (or licenses) than necessary.

Correct this bug building a planning of the evolution of the
constraints and then extracting the max amount of watts reserved
by potentially overlapping reservations.

Also correct a bug resulting in valid power check when more watts
than the defined powercap were reserved.
