spark-utils has table maintenance macros for DeltaLake tables.

For example these macros list the tables in a schema and perform vacuum.

In the same manner, it would be great if spark-utils also had support for Iceberg table maintenance.

Examples of maintenance could be

expire_snapshots
remove_orphan_files
rewrite_data_files
rewrite_manifests
