AccrueTime limits.

Bug 6002


Co-authored-by: Felip Moll <felip.moll@schedmd.com>

Regression introduced in ccafaf7b.

Replace the (was always set to true) check_current_dir argument to
search_path() with check_cwd_last boolean to indicate if cwd should be
evaluated first (needed by sbatch) or last (salloc/srun).

This patch also simplifies the code using bit_cnt instead of
_bitstr_bits().  This isn't really necessary, but does look cleaner.

Only print a warning for 18.08. If a user has SLURM_MEM_PER_CPU or
SLURM_MEM_PER_NODE environment variables set for some reason this
situation could be happening by accident, and we don't want to prevent
the srun command from launching steps at this point.

The Linux kernel default hard limit of 4096 for the number of file
descriptors is quite small. Debian/Ubuntu have for a long time
overridden this, increasing it to 1M. Recently systemd also bumped the
default to 512k.

Here the limits are increased as follows:

- slurmd: 128k; some workloads like Hadoop/Spark need a lot of fd's,
  and recommend that the limit is increased to at least 64k.

- slurmctld: 64k; per the Slurm high throughput and big system guides
  which recommend a file-max of at least 32k.

- slurmdbd: 64k, matching slurmctld, though slurmdbd shouldn't need
  that many fd's, bumping the limit shouldn't hurt either.

Bug 6155

When bf_continue is set, and locks are released during a backfill cycle,
other operations can make new resorces available while part way through
the queue. When backfill continues the cycle and evaluates new jobs, it
may allocate some of these newly available resources to lower priority jobs,
rather than to higher priority jobs that were already considered in this
backfill cycle.

This patch introduces bf_ignore_newly_avail_nodes to SchedulerParameters
to solve this issue. This option will ignore nodes made available when
the backfill scheduler yields when resuming the backfill cycle.

Plugins reading in their own config files rely on the SLURM_CONF
environment variable pointing to the appropriate directory,
otherwise they will fall back to the build in sysconfdir path.

Set the environment variable early enough so that the -f flag
operates correctly, but not before conf->conffile has definitely
been set. Remove the setenv call that happens before the first
slurmstepd is fork()'d as it is now redundant.

sbatch sets these, but salloc did not. This should make srun behavior
between the two consistent.
