An implementation of Function which acts as a gateway/router by actually delegating incoming invocation to a function specified via `function.name` message header.
Message is used as a canonical representation of a request which contains some metadata and it is the responsibility of the higher level framework to convert the incoming request into a Message. For example; spring-cloud-function-web will create Message from HttpRequest copying all HTTP headers as message headers.
