Autosharding - dogfooding

[chair28980]

Once the critical parts for autosharding has been implemented, we should dogfood the end-to-end operation. This could constitute a soft launch of the Waku Network with the first traffic relayed on all new network shards, albeit without any DoS mitigation mechanisms in place. Specific things to test include reviewing how well autosharding works with sharded discovery and bootstrapping (mechanisms that were developed previously for static sharding).

Priority: Critical for launch
