Comment 2 for bug 1554005

In order to ensure that stale rsync droppings are always cleaned up we can detect them in the auditor and remove them if they stat older than a configurable transfer time (default to rsync_timeout).

Example message from auditor detecting and ignoring these files currently reads:

Mar 8 01:18:35 saio object-6016: Unexpected file /srv/node1/sdb1/objects/645/35a/a161102fba1710ef912af194b8d4635a/.1457397409.69518.data.youuID: Invalid Timestamp value in filename '.1457397409.69518.data.youuID'
