EasyNetQ library

To prevent code duplication in Hangfire.SqlServer.RabbitMq and in tests wrapper for EventingBasicConsumer should be written. A ready solution exists: EasyNetQ library (https://github.com/EasyNetQ/EasyNetQ/wiki/Quick-Start):

```
static void Main(string[] args)
{
using (var bus = RabbitHutch.CreateBus("host=localhost"))
{
bus.Subscribe("test", HandleTextMessage);

Console.WriteLine("Listening for messages. Hit to quit.");
Console.ReadLine();
}
}

static void HandleTextMessage(TextMessage textMessage)
{
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine("Got message: {0}", textMessage.Text);
Console.ResetColor();
}
```

What do you think about adding it's reference to the solution and usage?

Start by reviewing the Hangfire.SqlServer.RabbitMq project and its tests, then compare the proposed EasyNetQ Quick Start usage with the existing EventingBasicConsumer code. Done should mean the reference and wrapper usage are agreed on and code duplication is reduced without breaking the existing tests.
