Seperate Queue Declare / Exchange Declare from Consumer Config

[pardahlman]

The new ConsumeConfiguration looks like this

public class ConsumeConfiguration
{
    public QueueConfiguration Queue { get; set; }
    public ExchangeConfiguration Exchange { get; set; }
    public bool NoAck { get; set; }
    public string ConsumerTag { get; set; }
    public string RoutingKey { get; set; }
    public bool NoLocal { get; set; }
    public ushort PrefetchCount { get; set; }
    public bool Exclusive { get; set; }
    public Dictionary<string, object> Arguments { get; set; }
}

Where Queue and Exchange contains information about types, durability etc. The ConsumerConfiguration should only contain properties for performing the consume. That is, Queue should be replaces with the string QueueName.

The fluent configuration builder should be updated to something like this

cfg => cfg
    .OnExchange("")
    .FromQueue("my_queue")
    .WithRoutingKey("herllo")

But still support declaring exchanges and queues

cfg => cfg
    .OnDeclaredExchange(e => e
        .WithName("my_exchange")
        .WithType(ExchangeType.Topic))
    .FromDeclaredQueue(q => q
        .WithName("my_queue")
        .WithAutoDelete())
    .WithRoutingKey("herllo")
    .WithPrefetchCount(50)
