Ian Cottrell 224c947ce5 internal/telemetry: replace TagSet with TagMap and TagPointer ... This separates the concerns of tag collections that have to be iterated and tag collections that need lookup by key. Also make it so that events just carry a plain slice of tags. We pass a TagMap down through the exporters and allow it to be extended on the way. We no longer need the event.Query method (or the event type) We now exclusivley use Key as the identity, and no longer have a common core implementation but just implement it directly in each type. This removes some confusion that was causing the same key through different paths to end up with a different identity.
