Original issue description below.
Description
Waku discovery5 implementation does random walks through the DHT and reports the discovered nodes. To support Waku relay static shards discovery, we want to announce in the ENR the shards the node is subscribed to and keep only the discovered nodes that match specific criteria (a.k.a. predicate).
