Tracking message-id and delivertag in Rabbit EventBus implementation

Hi All,
I know that EventBUS is an abstraction, and currently 2 implementations are supported Azure,RabbitMQ

regarding rabbitmq class [RabbitMQEventBus.cs](https://github.com/dotnet/eShop/blob/main/src/EventBusRabbitMQ/RabbitMQEventBus.cs
)

there are a couple of property that are very usefull to be tracked by the logger.logtrace

- delivery tag (internal number generated by rabbit client)

> - ` var deliveryTag = channel.NextPublishSeqNo;`

- properties.messageId (that could be set just to event.Id)

Registering these 2 properties in logtrace allows you to diagnose some annoying network error in /var/log/rabbitmq

Ciao
Diego
