Add an OTel span processor copying the 'trigger' baggage member propagated through contexts to all children spans. It's used to identify what triggered a trace / span (API call, libnet init, etc...) All code paths that call libnet's `NewNetwork` set this baggage member with a unique value. For instance, this can be used to distinguish bridge's `createNetwork` spans triggered by daemon / libnet initialization from custom network creation triggerd by an API call. Two util functions are added to wrap `baggage.New` and `baggage.NewMemberRaw` to make it easier to deal with baggage and members by panicking on error. These should not be used with dynamic values.
