    Handle file delete races in image cache
    
    In at least one case (see bug report) files have been deleted between
    when we check that they exist and when we actually attempt the deletion.
    Since we ultimately just want the file gone, we shouldn't care if we
    get an error that the file does not exist and just move on.

Title:
  Image cache clean should catch the not exist exception

Status in Glance:
  Fix Released

Bug description:
  For image cache clean, Glance will remove the invalid files and
  stalled files, but if there is a cron job and at the same time if the
  admin has removed one of file before the cron job deletes it. There
  will be a non existed exception. It's rare but possible. As a result,
  that will not clean the entire cache i think
