[Tutorial] Add a .NET RabbitMQ

[tomczoink]

RabbitMQ is a popular queue framework, so it'd be good to provide a tutorial for it as part of our existing queue tutorials. .NET would be a good choice of language.

Example connection code:

var connectionFactory = new ConnectionFactory {
HostName = settings.MessageQueueHostName,
Port = int.Parse(settings.MessageQueuePort),
VirtualHost = settings.MessageQueueVirtualHost,
UserName = settings.MessageQueueUserName,
Password = settings.MessageQueuePassword,
Ssl = new SslOption {
Enabled = true,
AcceptablePolicyErrors = SslPolicyErrors.RemoteCertificateNameMismatch,
Version = SslProtocols.Tls | SslProtocols.Tls11 | SslProtocols.Tls12
}
};
