Feat Sharding Replication

[conico974]

Implements sharding replication for the Durable Object tag cache.
Instead of being sharded only based on the tag, each shard will now also be replicated
This allow to scale way more (virtually infinitely)
A single tag could be read from any of the N random replicas associated with the tag shard.
On write we still need to write to every single replicas associated with this tag shard

Nice!
A few nits related to naming

[vicb]

I think we should be careful with naming things correctly to ease later evolutions and maintenance of the code.

I think we have shards, replicas and DOs.

Each shards has a soft and hard variant.
Those variants are replicated to distinct DOs when enableShardReplication is true.

I added a few inline comments, let's iterate.

Thanks!

Cool, thanks a lot for the updates 🚀
