Feature for micro service communication

The appc-service-communicator feature will be responsible
for communication between any appc microservices which are
developed.

The appc dmaap micro service connector is part of this feature.
MessagingConnector.java is the main new class here.

Some code is copied from appc event listener and dmaap adapter.
Will be moved in a later commit.
