unity-nfs-checker

• for each dir in dir_list, time how long it takes to ls
• do this once every loop_wait_time_s seconds
• if any of these times are greater than min_report_time_s, add a line to the report queue
• if there's anything in the queue,
  • and it's been more than max_email_frequency_min since the last email,
  • and email is enabled in the config
  • send an email containing the report queue, and clear the queue.
