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.

Save listing error async (#10922)
Since the RPC call may have to time out save an error state async 
to not hold up the listing returning.

Fixes #10919

listobjectversions: Add shortcut for Veeam blocks (#10893)
Add shortcut for `APN/1.0 Veeam/1.0 Backup/10.0`

It requests unique blocks with a specific prefix. We skip 
scanning the parent directory for more objects matching the prefix.

metacache: Add trashcan (#10820)
Add trashcan that keeps recently updated lists after bucket deletion.
All caches were deleted once a bucket was deleted, so caches still running would report errors. Now they are canceled.
Fix `.minio.sys` not being transient.

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* Caches are cleaned up when out of date or superseded by a more recent one.
