    CAMEL-7833 Use Camel endpoints inside RX sequence

    CamelOperator class allows us to use Camel endpoints inside an RX sequence, like so:
    
    ```
    Observable<Message> in = reactiveCamel.toObservable("direct:start")
       .lift(new CamelOperator(camelContext, "xslt:something.xsl"))
       .lift(new CamelOperator(anotherEndpoint));
    ```

> with Camel RX and java 8 we can do some nice lambdas and typesafe filtering and transformation:
> {code}
> ReactiveCamel rx = new ReactiveCamel(camelContext);
> Observable<Order> observable = rx.toObservable("seda:orders", Order.class);
>  
> // now lets filter and map using Java 8
> Observable<String> largeOrderIds = observable.
>   filter(order -> order.getAmount() > 100.0).
>   map(order -> order.getId());
>  
> rx.sendTo(observable, "activemq:MyQueue");
> {code}
> however the DSL isn't quite as nice as Camel's due to the lack of the camel verbs like "to()". It'd be nice to provide an extended Observable<T> interface which adds more of Camel's DSL in there too; so you can still use things the RX way; but can also reuse the camel DSL too (in a typesafe way). 
> e.g. something like this
> {code}
> // Observable comes from RX; it'd be nice to have a camel extended version so we can add camel DSL stuff in there like to() etc....
> CamelStream<Order> orders = rx.stream("seda:orders", Order.class);
>  
> // now lets filter and map using Java 8
> orders.
>   filter(order -> order.getAmount() > 100.0).
>   map(order -> order.getId()).
>   to("activemq:MyQueue");
> {code}
