Add job credential to "Run Prolog" RPC used with a configuration of
PrologFlags=alloc. This allows the Prolog to be passed identification of
GPUs allocated to the job.

Add SLURM_JOB_GPUS environment variable to those available in Prolog.
Also add list of environment variables available in the various
prologs and epilogs on the web page.

runjob happened, and the step was part of an array.  This is an addition to
commit 49e0f5f2

in the runjob_mux plugin.

Bug 1461
Commit: 2e2d924e

This completes work on the JSON parser for the capmc
get_power_cap_capabilities command, which reports specifics
about each node's power caps and ranges.

Add a find_node_record2() function that differs from
find_node_record() in that it does not print an error if
a node name is not found. This is important for use with
the Cray capmc command, which generates information about
not only compute nodes, but also login and service nodes.
Using this function prevents a bunch of errors from the
power/cray plugin when trying to find these non-compute
nodes in the slurm configuration.

See bug 1461

If call was made to change a node's state to the same state it
was already in and set its reason to the same value it already
had, then an accounting record was generated. If a script, say
NodeHealthCheck is repeatedly setting a node state (say DRAIN),
it could generate a huge number of redundant accounting records.
This eliminates these redundant records.

Bug 1446

Add SICP job hash table
Add logic to read SICP data from other clusters
Add state save/restore logic

don't insert a new row in the event table.

Bug 1321

Logic was logging a value before its value was set.
Bug found by CLANG.

The thread logic still needs to be fleshed out

There was a double lock (deadlock) in the power management plugin driver
The power and burst buffer plugins needed to be restarted whenever the primary slurmctld resumed control rather than once at daemon start time. Otherwise the backup and primary slurmctld could both try to manage power and burst buffer resources.

Add module for inter-cluster job development work
