Review Comment:
Let me add it here first:
What are involved?
1. A table with snapshots
2. A Polaris policy which indicates the snapshot expiry is enabled for the
table.
3. Table configuration or policy config indicates how to expire snapshots,
including parameters like max age of a snapshot.
4. An engine or client to able to remove expired snapshots, clean up files
for the table.
