Perform LFS S3 Delete outside of transaction

[nateiam]

As a Herd LFS user I want to minimize the amount of time that LFS operations hold database transactions so I can reduce the possibility that a concurrent user operation will receive an optimistic locking error.

Acceptance Criteria

• LFS file operation that occurs during clean-up does not hold a database transaction while performing the S3 delete operation
• Any failure in the S3 delete operation fails does not impact the database transaction that updates BData Status.
  • Note that current logic does not even react to failure of S3 delete operation – the transaction to update BData Status is committed either way. So there is no logical change and no reason to have the transaction around the S3 operation anyway.
