Rethink auto-dial logic for topic discovery in the network

[d-roak]

Currently, we are auto-dialing on discovery, with the DHT we'd still be dialing anything that's stored there. We need further considerations on the topic

The last comment around Relay in golang is really something we might want to implement one day.
Otherwise I think what we want is a place where peer can "search" for there DRP a bit like the rendezvous protocol but to find DRP and who are in this DRP

as a note in the connection manager settings there is this settings:

/**
   * Sort the known addresses of a peer before trying to dial, By default public
   * addresses will be dialled before private (e.g. loopback or LAN) addresses.
   */
  addressSorter?: AddressSorter

Maybe it could help us remove the sorting we have in identify
