logic to handle resize of jobs for steps and suspended jobs.  suspended job logic hasn't been tested

    addition to the currently accepted "minutes", "hours", etc.

default partition was not idle. new logic tests every node in the 
default partition for an idle one.

  and use this to rebuilt the node bitmap on slurmctld econfigure or
  restart. This is needed to insure consistency with the other bitmaps
  (e.g. cpu count per allocated node).

ok, it appears things are handled correctly for jobs when they resize, it is still needed to add steps resizing

the node_bitmap will remain unchanged, but cpus, cpus_used, cpus_array_*, 
and memory_used will be updated (e.g. cpus and mem_used on that node cleared).

    accounting record is being written immediately before or after it changes
    size. This permits job accounting records to be written for a job at each
    size.
Make calls to jobcomp and accounting_storage plugins before and after a job
    changes size (with the job state being JOB_RESIZING).All plugins write a
    record for the job at each size with intermediate job states being
    JOB_RESIZING. More work is needed for correct accounting.
