Wrong check for binding and match in consumer configuration validation

[Raibaz]

I was trying to move my consumer configuration outside of the code and into the application.yml file, but i stumbled with an issue in configuration validation.

According to the documentation, the following configuration should be valid for a queue consumer:

VehicleConsumer:
    queue: 'vehiclesQueue-it'

But the ConsumerConfigurationImpl class does this check when validating the configuration.

However, the binding and match properties shouldn't be required when binding a consumer to a queue. Adding them to my yml configuration with bogus values makes the validation pass, but IMHO the check should be fixed.

Note: i did some debugging and noted that when loading configuration from a yml file the binding property is populated with an empty Map instead of being null, so the check fails. Thus, to make the validation pass it's sufficient to add the match property to the consumer configurations, but it shouldn't be needed anyway.
