feat: remove dht publication

[Freyskeyd]

Description

This PR removes the DHT publication of the addresses of the node on the Kademlia DHT.
It is not needed anymore as we rely on gossipsub for the broadcast and on gRPC over p2p for anything else.

PR Checklist:

• I have performed a self-review of my code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation
• I have added or updated tests that comprehensively prove my change is effective or that my feature works

Would be nice to comment the current_bootstrap_id. Question also: Why current_*? And the type is QueryId. Should we rename it then to query_id?
