Simplify the remote-outbound connections

At the moment the application need to reference each outbound connection with a remote-ejb-receiver element in the jboss-ejb-client.xml.
But from an application perspective it is not relevant whether the server environment provide one or many receivers or whether the ejb-receiver is a cluster.
It should be possible to add many outbound-socket-binding-ref elements and related properties to the remote-outbound-connection element of the server configuration.
In this case it is possible to keep the application deployment independent from the server environment.
