Bug 4105

The task/cgroup plugin sets the UID patch based upon the pack_jobid
   (if a pack job). This is needed for Cray systems.

Bug 4105

Without this change, a step that did not use heterogeneous job
  component zero would not run

For a pack step launch with one job component, always set pack_jobid
   field and all of the other "pack_" fields. This will be needed
   for Cray support.

Previously scontrol update PartitionName=* MaxNodes=* would
print an error and exit of the MaxNodes value was invalid (e.g.
not a number). Now it prints an error and can continue, say
processing multiple requests in a script

Bug 6873

When specifying -j and not -s then non-eligible jobs will be shown
by sacct.
Time windows can also be used with -S and -E.
If --state is also used then non-eligible jobs won't be shown,
because non-eligible are not actually PD.

Query fixed to handle properly these cases for -s PD.
