Title: INT-3550: RoutingSlip improvements

JIRA: https://jira.spring.io/browse/INT-3550

* Make `RoutingSlipRouteStrategy#getNextPath` as `Object` return type. to allow to produce `MessageChannel` result, not only `beanName`
* Make `RoutingSlipHeaderValueMessageProcessor` ctor to accept `Object... routingSlipPath` instead of just String.
It is useful from JavaConfig, when we can use `RoutingSlipRouteStrategy` `@Bean` reference.
* Add JavaConfig test case to demonstrate how `RoutingSlipRouteStrategy` can get deal with inline `FixedSubscriberChannel`
and Lambdas together with Reactor Streams.
