Description
Hive conenctor supports `CachingDirectoryLister` - [https://github.com/trinodb/trino/blob/8bb87dd44820774040927aa872eeaddc62830b87/plugin/trino-hive/src/main/java/io/trino/plugin/hive/fs/CachingDirectoryLister.java]
Hudi connector should also support metadata caching. This is particularly useful when running repeated queries on the same table in the same session.

Research direction
Start with the Hudi connector's metadata and directory-listing entry points, then compare the referenced Trino file, plugin/trino-hive/src/main/java/io/trino/plugin/hive/fs/CachingDirectoryLister.java. Check the Hudi connector tests around repeated table queries and add coverage showing that metadata is reused within one session.
