### Is your feature request related to a problem or challenge? When using the `ListingTable` the objects backing the table are listed on each query. This inherently adds additional latency to every query, and this latency is especially notable when using high-latency storage such as remote Object Stores. DataFusion's cache infrastructure for `ListingTable`s has a hook for a `ListFilesCache` that users can implement, however there is no default implementation. I would like to improve out-of-the-box query performance by providing a default implementation for the `ListFilesCache`. ### Describe the solution you'd like I would like a default implementation of the `ListFilesCache` that mirrors the functionality of the recently developed `MetadataCache`. This implementation should have a user configurable memory bound and users who do not want to use the cache should be able to disable it. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
