Hook with fusion into the lifecycle events and signals of a Mono and execute a provided callback after any of onComplete, onError and cancel events. The hook is executed only once and receives the event type that triggered it (SignalType.ON_COMPLETE, SignalType.ON_ERROR or SignalType.CANCEL).

Note that any exception thrown by the hook are caught and bubbled up using Operators.onErrorDropped(Throwable, Context).
