The test is still failing for me (along with a bunch of others),
  but this change at least gets the test started.

a slurmctld restart or reconfig, as they aren't really error messages.

Done jost to run "git push" again after internal github error on
  previous push:
remote: Resolving deltas: 100% (4/4), completed with 4 local objects.
remote: Unexpected system error after push was received.
remote: These changes may not be reflected on github.com!
remote: Your unique error code: bdecb7b0f321368fe1f037a81a6e9c2c

This restores the socket count check at node registration for
  non-KNL systems (at least systems without NodeFeaturesPlugins
  type that includes "knl"). This is a refinement of commit
  1ce9a7c4

Note that this does not protect against all possible problems here.
The setgroups() call in Linux at least is willing to set any gid_t
value except -1 on a group, so calls will not always fail on corrupted
group lists.

Bug 3320.

Remove uncached _get_grouplist() call which was only used here.

Bug 3315.

test12.2 was consistently failing on smd# cluster with tiny differences
  in the disk read and written. This change permits those tiny discrepancies
  to exist without failing the test.
  Here are the numbers, which are consistent:

  sacct --noheader -p --job=763.0 --format MaxDiskWrite,AveDiskWrite,MaxDiskRead,AveDiskRead
  10.00M|10.00M|10.03M|10.03M|
  (i.e. 0.3% discrepancy, up to 0.5% allowed with current code)

Test was failing due to hitting the memory limit (at least on smd1).

There were already several configurations that could cause this test
  to fail. I just added another.

Fix parsing in regression test1.92 for some prompts.
bug 2792

Recognize a KNL's proper NUMA count (rather than setting it to the value
    in slurm.conf) when using FastSchedule=0. Previous logic would change
    the NUMA count on the node to match what was in slurm.conf, which would
    mess up task layout with respect to the sockets.
