issue with gang scheduling.

Bug 3211

Federated submissions

Fix bug that was clearing MAINT mode on nodes scheduled for reboot (bug
    introduced in version 16.05.5 to address bug in overlapping reservations,
    commit 5eee1d28). Note that a node's
    MAINT flag is used for both a requested reboot and maintenance reservation.
    What I'd like to do is add a new node state flag to differenciate
    between these two cases, but that involves some significant changes
    that could introduce instability, so it will be defered to version
    17.02

salloc are requested with -n tasks < hosts from -w hostlist or from -N.

requested with -n tasks < hosts from -w hostlist.

bug 2149

Add new SchedulerParameter (max_array_tasks) to limit the maximum number of
    tasks in a job array independently from the maximum task ID (MaxArraySize).

Bug 3194

Add SbcastParameters configuration option to control default file
    destination directory and compression algorithm.
bug 2977

Replace sjstat, seff and sjobexit RPM packages with a single "contribs"
    package.

Remove separate slurm_blcr package. If Slurm is build with BLCR support,
    the files will now be part of the main Slurm packages.

Document that node Weight takes precedence over load with LLN scheduling.
bug 3204

Follow on to commit c3266fca for 17.02+.

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.

Bug 3154.

Do not include SLURM_JOB_DERIVED_EC, SLURM_JOB_EXIT_CODE, or
    SLURM_JOB_EXIT_CODE in PrologSlurmctld environment (not available yet).
bug 1431

burst_buffer/cray: Accept new jobs on backup slurmctld daemon without access
    to dw_wlm_cli command. No burst buffer actions will take place. Newly
    submitted jobs will be accepted and stay in pending state. Jobs depedent
    upon stage-in or stage-out will remain in their current state until the
    action can take place.

Do not process SALLOC_HINT, SBATCH_HINT or SLURM_HINT environment variables
    if any of the following salloc, sbatch or srun command line options are
    specified: -B, --cpu_bind, --hint, --ntasks-per-core, or --threads-per-core.bug 3118

_select_nodes_parts() was resetting state_reason to an admin hold
without regard to admin vs user hold state. state_reason is the only
place that user vs. admin is distinguished, so this prevented users
from releasing these jobs.

Bug introduced by commit fb46c84b in 16.05.5.

Bug 3197.

This is an addition to commit cb7ed937

bug 3191

bug 3192

Continuation of commit 2fd4d7a6. MySQL dropped support for 'ignore',
unconditionally remove that to avoid issues with mismatching client + server
versions like in bug 3189.

Improve reported estimates of start and end times for pending jobs.
bug 3184

Cray: Prevent abort in backfill scheduling logic for requeued job that has
    been cancelled while NHC is running.
bug 3185

Old command line would not work with FreeBSD. New command line
  should work with all systems
bug 3021

Add mechanism to constrain kernel memory allocation using cgroups. New
    cgroup.conf parameters added: ConstrainKmemSpace, MaxKmemPercent, and
    MinKmemSpace.
bug 2917

new glibc 2.24+ that depricates readdir_r.

Add suppoprt for --mem_bind=prefer option to prefer, but not restrict memory
    use to the identified NUMA node.
bug 3126

Modify cpu_bind and mem_bind map and mask options to accept a repetition
    count to better support large task count. For example:
    "mask_mem:0x0f*2,0xf0*2" is equivalent to "mask_mem:0x0f,0x0f,0xf0,0xf0"
bug 3065

Added node_features/knl_generic plugin for KNL support on non-Cray systems.
NOTE: This plugin is still under development.

Do not propagate SLURM_UMASK environment variable to batch script.
bug 2609

task/affinity plugin: Honor a job's --ntasks-per-socket and
    --ntasks-per-core options in task binding.
bug 3118

Correct a bitmap test function (used only by the select/bluegene plugin).
  The effect of this bug is probably very limited as it will in almost
  all cases revert prematurely to a bit-by-bit test rather than using
  a full-word test.
bug 3145

Cannot use ClusterName without reading a config file
that may not exist.

Bug 3026.

This introduced an inadvertent dependency on the config file,
which does not exist when setting up a new cluster.

Bug 3026.

This reverts commit c39f9ac9.
