Cleanup KafkaUtils and upgrade to Kafka 10

[jtbarbetta]

We need Kafka 10+ for MessageBroker so we also need to upgrade KafkaUtils to use new org.apache.spark.streaming.kafka010 package that corresponds.

On the client-side of EclairJS we ran into a classloader issue within Toree the prevented us from upgrading to version 10 of the kafka-streaming package in KafkaUtils. For our 0.9 release we had to write our own custom KafkaUtils/kafka receiver. Once the Toree issue is resolved we can try using org.apache.spark.streaming.kafka010 again, thus leaving this opened unti then.
