    13546: crunch-job has timeout on srun_sync
    
    * Add global timeout to srun_sync, default 15 minutes, terminates
      job if a call to srun_sync exceeds the timeout.
    
    * Default can be adjusted by setting CRUNCH_SRUN_SYNC_TIMEOUT in the
      environment of crunch_dispatch.rb (value is in seconds)
