    CAMEL-9824 Add URI parameter to declare server named queues

    As described in CAMEL-9824 We need a possibility to declare server named queues. 
    
    To achieve this I would like to add a new URI parameter "serverNamedQueue".
    
    If this parameter is set, the queue is declared via 
    `channel.queueDeclare();`
     instead of 
    `channel.queueDeclare(queue, endpoint.isDurable(), false, endpoint.isAutoDelete(), arguments);`
    
    The drawback of this solution is that several other options (isDurable etc) are ignored.
If someone has a different idea on how to solve this I am more than happy to hear it!

>             Project: Camel
>          Issue Type: Improvement
>          Components: camel-rabbitmq
>    Affects Versions: 2.17.0
>            Reporter: Fabian Chanton
>            Priority: Minor
>
> This problem is similar to CAMEL-9815
> For a project we have to declare a queue without a name. The server then auto-generates
a random name and passes it back.
> If we do not specify a queue name, RabbitMQEndpoint defines a random name for us. This
however is not allowed on the server.
> I locally tried a fix for RabbitMQDeclareSupport, where instead of using 
> {code:java}
>         channel.queueDeclare(queue, endpoint.isDurable(), false, endpoint.isAutoDelete(),
arguments);
>         channel.queueBind(queue, exchange, emptyIfNull(routingKey));
> {code}
> i declare the queue like this:
> {code:java}
>       DeclareOk declareOk = channel.queueDeclare();
>       endpoint.setQueue(declareOk.getQueue());
> {code}
> This has some drawbacks, as it completely ignores endpoint.isDurable(), endpoint.isAutoDelete()
etc. and even the routing key is ignored.
> I don't know how to best add a possibility to declare server named queues.
