metacache: Add option for life extension (#10837 )

Add `MINIO_API_EXTEND_LIST_CACHE_LIFE` that will extend 
the life of generated caches for a while.

This changes caches to remain valid until no updates have been 
received for the specified time plus a fixed margin.

This also changes the caches from being invalidated when the *first* 
set finishes until the *last* set has finished plus the specified time 
has passed.

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* Caches are cleaned up when out of date or superseded by a more recent one.
