keep from-serge tar file history for some time
Serge sends regularly to polyanthum a tar file with the latest descriptors. In polyanthum we process the tar and send it with a timestamp to collector. There might be issues with the sending, will be nice to keep a copy of each uploaded tar to collector for some time so we can restore if needed.
