EventHubSpout does not support consumergroups and/or user-properties

[yorgovs]

When using the evenhubspout there is no option to configure a certain consumergroup. However, this option is available in the Java implementation. It is not included in the constructor, but it is available as a property. Can this property be made available through SCP?

On top of that, the eventhubspout only returns the eventdata's message, the user-properties, partitionkey, etc. are not included in the tuple. However these are certainly transmitted. This is probably due to the Java implementation of the spout.

The latest update of storm-eventhubs addressed these issues.

• Consumer group usage and fluent api: https://github.com/hdinsight/storm-eventhubs/issues/8
• You can use clojure expression to use an alternative "EventDataScheme" or "BinaryEventDataScheme" to get metadata in a separate field. This may need little more work since we need to create metadata in a compatible C# data type so that the JSON serializer and deserializer can handle that.
