Fix kafkajs Node metric format

[bizob2828]

Description

We thought we were following the spec for the Kakfa node metrics but we added an extra /Named to the metric name. This was preventing the AWS entity relationship from properly linking

Acceptance Criteria

Create metrics for every consume or produce in the following format

MessageBroker/Kafka/Nodes/{server_name}/Produce/{topic_name} 
MessageBroker/Kafka/Nodes/{server_name}/Consume/{topic_name}
