Bug 6229

this new function adds logic to validate that a job's gres request is
still valid after slurmctld restart or reconfiguration. specifically
if a job allocation includes GRES associated with specific Files then
kill the job if the GRES count changes (say the job is allocated GPUs
and the slurmctld configuration changes to remove those GPUs, so the
job and node bitmaps are different sizes).

This prevents a slurmctld abort if a job was running on a node
  using all gres/gpu and the node configuration changed to have
  fewer gres/gpu. slurmctld would abort on restart with the new
  configuration.

Previous logic was calculating a node's total cores and total threads
in multiple locations rather than doing the calculation only in the
function gres_plugin_node_config_validate().

Move some common logic from gres/gpu and gres/mps into gres/common
Eliminate some redundant string copy/free logic
Remove gres/gpu record combintation logic, which will not work with
