      Description

      Sometimes, when an FTS transfer fails, it may leave an incomplete file at the destination.
      This scenario has been seen frequently in transfers involving the CAST VO.

      The disadvantage is that unless the overwrite flag is set, FTS retries have no change of succeeding, as they will be met with "Destination file exists and overwrite is not enabled".

      The proposal is to introduce an additional flag overwrite_on_retry which will enable the overwrite flag only during FTS retries.

      With this flag, the user can avoid the undesirable overwrite during the first submission (e.g.: when transferring to tape, caution is advised), but still give the FTS retry mechanism a chance to succeed.
