Since API v2 not support tags/labels on Snapshot:
Unlike previous versions of snap-o-matic, v0.02 and later will not preserve user-created snapshots.
snap-o-matic will delete the oldest snapshots during rotation and it will not differentiate
between snapshots created by snap-o-matic or by the user.

• -L LOG_LEVEL or --log-level LOG_LEVEL: Logging level, supported values: error,info,debug (default info).
• -r NUMBER or --snapshot-retention NUMBER: Maximum snapshots to keep (default 7).

Credentials can be passed either as a credentials file, or as environment variables. Supported environment variables:

• EXOSCALE_API_KEY: Exoscale API key.
• EXOSCALE_API_SECRET: Exoscale API secret.
