Couple of azure eventhubs customers using apache-nifi-processor are running into known issues fixed in later versions. So updating the version to the latest - for the next release to pick this up.

Hi @SreeramGarlapati, thanks for your contribution. I looked at the release notes from
https://github.com/Azure/azure-event-hubs-java/
And it seems there are few breaking changes between 0.9.0 and 0.14.0.

In particular:

• The EventData.ApplicationProperties is now a Map<String, object>.
• Simplified EventData by deprecating the getBody* API's. As such, the following methods have been deprecated:
  EventData.getBody() replaced with EventData.getBytes()
EventData.getBodyOffset()
EventData.getBodyLength()

I think we are only concerned by the deprecation of the getBody() that should be replaced by getBytes() in GetAzureEventHub. Could you take care of that?

Otherwise, I did few tests and it seems to be working as expected.

Thanks!

Also, right now, 0.14.2 is available, I'd suggest to go with this version.
