metacache: Allow prefix filtering (#10920 )

Do listings with prefix filter when bloom filter is dirty.

This will forward the prefix filter to the lister which will make it 
only scan the folders/objects with the specified prefix.

If we have a clean bloom filter we try to build a more generally 
useful cache so in that case, we will list all objects/folders.

ListObjects Metadata Caching (#10648 )

Design: https://gist.github.com/klauspost/025c09b48ed4a1293c917cecfabdf21c

Gist of improvements:

* Cross-server caching and listing will use the same data across servers and requests.
* Lists can be arbitrarily resumed at a constant speed.
* Metadata for all files scanned is stored for streaming retrieval.
* The existing bloom filters controlled by the crawler is used for validating caches.
* Concurrent requests for the same data (or parts of it) will not spawn additional walkers.
* Listing a subdirectory of an existing recursive cache will use the cache.
* All listing operations are fully streamable so the number of objects in a bucket no 
  longer dictates the amount of memory.
* Listings can be handled by any server within the cluster.
* Caches are cleaned up when out of date or superseded by a more recent one.
