Goal:

• We should delete all snapshots that are older than some preconfigured time, likely 365 days for production, some smaller amount for stage (~90 days).
• For now this does not need to be controlled on a per-org basis, but it may be nice to design this so it could be changed in the future.

Acceptance Criteria:

• Automatically remove snapshots that are older than 365 days for production, 90 days for stage
• Show a warning on a template if it is using a snapshot approaching deletion (within 30 days)
