Backups

[davissp14]

Right now, we are performing volume-based snapshots every 24 hours and sending them up to s3. This is a good start, but we have a few things that need to happen before this is useful for the end-user.

MVP

• [x] Expose snapshots through flyctl https://fly.io/docs/getting-started/multi-region-databases/#listing-snapshots
• [ ] Snapshots should be downloadable
• [ ] Snapshots should be able to be made on-demand
• [ ] Come up with a retention strategy.

Perhaps also help with rotation? ("keep ${daily,weekly,monthly} backups for ${180 days, 12 months}")
