Convert Consumer<Foo> to Function<Flux<Foo>,Mono<Void>>

Browse Source 
This results in a better experience for users because the consumer
that they write is only applied to a Flux that is subscribed to
by the framework once. It gives better control over the flow of
foos, e.g. if some component wants to subscribe on a thread.
