E.g. here:

bb.lg.Warn("HandleResolvedAddrs called with error", zap.String("balancer-id", bb.id), zap.Error(err))

My goal here was to avoid a big diff in .go source files to make it easier for maintainers to grok what has changed. Notice that HandleResolvedAddrs() is no longer part of the Balancer interface:

So we could just rename HandleResolvedAddrs() to UpdateClientConnState() and just return err after some / all of the bb.lg.Warn() statements.

return nil

Ditto here on rename / repurpose of old code. HandleSubConnStateChange() is gone from the Balancer interface so we could just implement that here.
