  tier for if data is already present before setting up autotier.

autotier 1.1.4 (preview)

autotier 1.1.4

• Tiering of files is automatically triggered if tier is over quota after
  writing to a file. To disable, added config option Strict Period = true.
• Added disabling of tier period by setting to a negative number so a cron
  job for autotier oneshot can be used to trigger tiering.

  filesystem rather than just printing contents of file.
• Implemented parallel moving of files while tiering with one thread per
  tier for maximum concurrency.
• Fix bug where readdir was still showing backend autotier files.

  while moving files between tiers.
