• broker - A http handler which implements the go-micro broker interface
• cloudevents - Handles CloudEvents and publishes to a message bus.
• event - Handles any HTTP request and publishes to a message bus.
• http - Handles any HTTP request and forwards as a reverse proxy.
• registry - A http handler which implements the go-micro registry interface
• rpc - Handles json and protobuf POST requests. Forwards as RPC.
