[I] Maintenance: Expire Snapshots Action [iceberg-rust]
cmcarthur opened a new issue, #1454:
URL: https://github.com/apache/iceberg-rust/issues/1454
### Is your feature request related to a problem or challenge?
Implement an ExpireSnapshotsAction with similar configuration options and outputs to the Spark expire snapshots procedure. Part of https://github.com/apache/iceberg-rust/issues/1453.
### Describe the solution you'd like
An expire snapshots action that takes the following inputs:
- `older_than_ms`: A timestamp in milliseconds, specifying the retention window for snapshots
- `retain_last`: Minimum number of snapshots to retain
- `max_concurrent_deletes`: Maximum number of concurrent file deletions
- `snapshot_ids`: A specific list of snapshot IDs to expire
- `dry_run`: A flag allowing a preview of snapshot expiry
It is important that this action both write a new metadata version with snapshots expired, _and_ followup and delete any now-unreferenced files. This will keep both the latest metadata and the metadata directory clean.
### Willingness to contribute
