Review Comment:
We discussed this internally and concluded that this parameter isn't
actually necessary. In this PR, we plan to remove it directly. For data lake
scenarios, tables not on the whitelist won't be cached. For internal table
scenarios, tables not on the blacklist will be cached. If configuration needs
to be provided in the future, it should differentiate between data lake and
internal tables, and this can be considered together with the modifications to
enable_file_cache and disable_file_cache.
