If you're creating a bug/problem report, please include followings:

• Abp version3.2.1.

With RabbitMQ.Client, we can connect to a MQ cluster.

    var connectionFactory = new ConnectionFactory()
    {
          UserName = "guest",
          Password = "guest"
    };  
    var connection = connectionFactory.CreateConnection(new string[] {
    "192.168.23.149",
    "192.168.23.144",
    "192.168.23.143"
     });
     var channel = connection.CreateModel(); 

But in abp configuration, it's only support something like this,

{
  "RabbitMQ": {
    "Connections": {
      "Default": {
        "HostName": "192.168.23.149",
        "Port": "5672"
      }
    }
  }
}

How to acheive it?

looks like in Volo.Abp.RabbitMQ.ConnectionPool Get Method, it use ConnectionFactory.CreateConnection() hardcoded,
it would be better if we can change to use ConnectionFactory.CreateConnection(hostnames[])
