Fix sched/wiki2 to support job account name, gres, partition name, wckey,
or working directory that contains "#" (a job record separator). Without
this patch, the parsing will probably stop once reaching the "#".

configuration in this case, and it ignores what the actual hardware is
because in this situation the slurmctld needs to make a bunch of bitmaps
before the slurmd's register.

These changes reduce the overhead of some functions for improved
slurmctld throughput.

Overhead of slurm_preempt_init() goes from 20% of CPU time to NIL

from 12% of CPU time to NIL.

While safeguards are in place to prevent unauthorized users from extending the
TimeLimit of their running jobs, there were no such restrictions for extending
the EndTime.  This patch adds the same constraints to modifying EndTime that
currently exists for modifying TimeLimit.

The new function permits API users to specify a non-default MPI plugin
before any other APIs launch the default plugin.

Add documentation for the mpi/pmi2 plugin.
Minor changes to code formatting and logic, but old code should work fine.
