QueueingConsumer class is deprecated and might be replaced

[MichaelRoeder]

Description

The RabbitMQ client class QueueingConsumer used in our implementation is marked deprecated in favor of a the DefaultConsumer implementation (see https://github.com/rabbitmq/rabbitmq-java-client/blob/v4.8.0/src/main/java/com/rabbitmq/client/QueueingConsumer.java#L64-L92). It might be necessary to replace the implementation in the future since deprecated classes can be removed from projects.

This mainly affects the classes

• https://github.com/hobbit-project/core/blob/master/src/main/java/org/hobbit/core/rabbit/DataReceiverImpl.java
• https://github.com/hobbit-project/core/blob/master/src/test/java/org/hobbit/core/rabbit/SenderReceiverTest.java

Create a custom class CustomConsumer which extends DefaultConsumer class and override the method handleDelivery to add each delivery to a public class variable LinkedBlockingQueue deliveryQueue. Which will be used to fetch deliveries.

@sourabhpoddar404 and @altafhusen-mr Please do not simply make the queue attribute public. Try to abide to the ideas of object-oriented programming by keeping the queue private (or at least protected) and enable access by offering methods which allow only the necessary methods.

Sure @MichaelRoeder we'll update it accordingly.
