[doc] connections are not distributed across broker pods when going through the amqp route

We have configured a service as advised in this KB[1]
 
The service is installed as expected and the two broker pods'ip are in the Endpoint.
We have  created multiple connections using the amqp route from a client located outside OpenShift.
We expect connections to be distributed among the different broker nodes.
W have 2 broker pods.

Here is my client code (snipped):

        List<Connection> list = new ArrayList<>();
        for (int i = 0; i < 20; i++)

{             list.add(connectionFactory.createConnection(user, password));         }

        Thread.sleep(30000);
        for (Connection connection : list)

{             connection.close();         }

so, when we create 20 connections, I expect 10 on each broker node.
What we see is that all connections get created on the same node while using amqp.

The following case has been created regarding this issue that seems like a bug with amqp
