Improves the ability to perform resharding by switching the sharding struct from array to map. Each map entry has a key which is used in rendezvous hashing to deterministically select which shard to use from the collection of keys. When a shard is removed it is guaranteed that only blobs which belonged to the removed shard will resolve to a new shard. In combination with ReadFallbackConfigurations this allows adding and removing shards with minimal need to rebalance the blobs between the shards. See https://github.com/buildbarn/bb-adrs buildbarn#11 for more details.
