Main change

Before, watchTopicShards would directly call wenr.Update:

logos-messaging-go/waku/v2/node/localnode.go

Line 392 in 8b0e031

err = wenr.Update(w.log, w.localNode, wenr.WithWakuRelaySharding(rs[0]))

This was bad, because:

1. It is done async, there is a race condition with enr.WithMultiaddress implementation.
2. It did not check for ENR 300 bytes limit

Now LocalNode entries are only modified through UpdateLocalNode.
This way we ensure the order of adding ENR options, making multiaddrs go the last.

Both issue (race condition and 300 bytes limit) solved.

Refactoring

• Refactored UpdateLocalNode to take LocalNodeParams arguments structure
• Removed UpdateLocalNode duplication (there was a copy in enr tests)
• To prevent import cycle I had to move some functions into node/utils params
