Title:
  OpenStack datasource should not retry user-data on 404

Status in cloud-init:
  Fix Released

Bug description:
  When receiving a 404 from user_data attempts, cloud-init should not
  attempt to retry the errant user_data file as it is wasted effort.  If
  the metadata service is already up, then any user-data should already
  be present, so a 404 at this time means that no user data exists so
  retries will not result in finding  user-data at a later time.

  Excerpt of logs indicating metadata is up but user-data does not
  exist:
