The pid files in slurm.conf and the systemd service files must match,
or systemd will time out looking for the wrong pid file. Currently,
the Cray slurm.conf template has different pid files for slurmctld and
slurmd than the service files.

There's no reason for us to use these nonstandard pid files, and it
will save us some headaches to switch over.

Due to the way Cray builds Slurm, the prefix and bindir paths include the
Slurm version (/opt/slurm/<version>). This means every time we update to a
new Slurm version we must update the Slurm ansible playbook. It also means
that the slurm_playbook.yaml file must be built with Slurm to be used
(it can't simply be copied directly).

The attached patch updates the playbook to determine the version of Slurm
to use from the module file, and hardcodes the sysconfdir setting we give
in our Slurm installation guide. If a customer uses different paths, they
can update the playbook to meet their needs.

On CLE 6.0 mungedir is /usr; a 'module unload' call then removes /usr/bin
from PATH which is rather inconvenient.

Bug 4334.

Kept separate for clarity.

This was needed for older versions of MUNGE, but has not been required
since 2010 / 0.5.9.

Deprecate BG/Q and Cray/ALPS modes. You must use --enable-deprecated
to build with these options from now on, or the build will error
out with a warning about the upcoming removal of these platforms.

Bug 4233.

Enforce this assumption at configure time; if this is not true
there are some serious security risks that would result.

Cygwin removal previously done in ada78c4e, but the configure
script was defined.

Solaris is a dead platform; commits to remove last traces of it
will follow.

In order to test with larger systems, modify capmc script to generate
  output with arbitrary start and end NID values

capmc_resume (Cray resume node script) - Do not disable changing a node's
    active features if SyscfgPath is configured in the knl.conf file.
bug 3533

CRAY systems only: TaskPlugins must list task/cgroup before task/cray in
    order for the cgroup files to be created before task/cray runs. Without
    this change, the task/cray plugin frequently produces errors about the
    "mems" file being missing. The errors don't seem consistent, so this
    probably involves a race condition. Note that NERSC uses this order
    today and I changed read_config.c to produce a fatal error if the order
    is reversed.

Add new knl.conf parameter to the capmc_suspend and capmc_resume
  programs. They are not used by those programs, but we need to
  prevent an error if those new parameters are used.

Remove req_node_layout, which was only used with wiki/wiki2.
This leads to removal of _get_cpu_cnt() as well.

Remove SchedulerPort, only used for communication to Moab/Maui.
Remove slurm_get_sched_port() from API.
Remove schedport from slurm_ctl_conf struct.

task/cray's _get_numa_nodes() function needs to run before task/cgroup
cleans up the cgroup hierarchies, otherwise ALPS memory compaction will
never run.

Also move task_p_add_pid() outside the #ifdef HAVE_NATIVE_CRAY
block so that the plugin will load (albeit without any functionality)
on non-Cray systems for testing purposes.

Revise documentation and provided slurm.conf templates as well.

Add new knl.conf configuration parameter CapmcRetries
Modify capmc_suspend and capmc_resume to retry operations when
  Cray State Manager is down.
Add retry logic to node_features/knl_cray to handle Cray State
  manager being down.
