pkill without -x option treats argument as a pattern in this case
slurmd matches not only slurmd but also slurmdbd.

i.e.

gres=gpu:k80:4,gpu:tesla:4

the code would put the k80 as one number 4, and then add the tesla and
not remove the 4 but add the 8 so if all your other nodes only have 1
gpu and you are asking for 2 nodes it would return 4 instead of 1.

This is a continuation of commit edd09b55.

Bug 7071.

Documentation for "-d" was missing from the man page.
Documentation for "-i" was missing from "slurmctld -h".
Sync the description for "-D".

Bug 7245.

Instead of scontrol show daemon for logrotate we can just use list
of all daemons. This should be less confusing for users since slurmdbd
is not listed by scontrol show daemons and required separate logrotate
configuration.

Bug 6962

The init() function creates a separate thread that tries to index the
list of unindexed jobs (loaded from the state or newly finished) into
the elasticsearch server. This fix prevents this thread from trying to
do so until after slurm_jobcomp_set_location sets the log_url.

Bug 7153.

Also added TimeEligible as a field that can be requested.
Bug 7074

If all runaway jobs have submit_time=0, something is wrong, and we
don't know from when to reroll the usage tables.
Bug 7074

When fixing runaway jobs, submit time should always be set in the
database, so use that when rerolling usage. Avoids rerolling from 0.

If bf_min_prio_reserve was not the last option listed, the setting would
not have been applied correctly, and an error message printed instead.

Catch jobs with empty pack_job_id_sets.
Corruption bug fixed by previous commit.

Bug 6847

Rejected hetjobs were not correctly dump because pack_job_id_set was
not properly set in _slurm_rpc_allocate_pack() when submision was
rejected.

New helper function _create_pack_job_id_set() to avoid duplicated
code.
