title: Use options set on apache camel direct endpoint
body: <p>I am building a routing slip bean and want to apart from the dynamic routing also to send a parameter to the endpoints of the recipients list.</p>
  
  <p>I wish to use something like "direct:test?param=value", where param and value are set inside the routing slip POJO</p>
  
  <p>From what I understand from the direct component, a single "direct:test" endpoint will receive all the routed exchanges, however I need a way to read the param send from the routing slip </p>
  
  <p>How can I use this param to the endpoint which receives the exchange? Is it a property of the exchange?</p>
