Expose event delegate for clients to handle connection issues

[mocsharp]

Description

Expose ConnectionErrorHandler event delegate for IMessageBrokerSubscriberService users to handle connection issues.
The users would need to call Subscribe or SubscribeAsync in order to attach their callback to the new connection model.

For RabbitMQ, the RabbitMQMessageSubscriberService recreates a new channel on model shutdown. If connection cannot be established, it will retry forever (every second) until it's able to reconnect.
