Backup story for TRSS server

The current TRSS server https://trss.adoptopenjdk.net/ is down for almost two days. And we cannot ping the machine. While people are looking into the issue, we need to have a backup story for TRSS server (in case this happens again in the future).

This backup story will include not only quick bring up of a new server, but a schedule for backing up mongodb on the backend (so we have test history available in the new instance).
