For efficiency we're using the Kafka clients send_messages function which takes a variable number of messages to send and batches them so that they can be read one at a time. To do this we use the * operator to expand the list of metrics as we pass them to the send_messages function. If the input data is not a list this doesn't work so even single metrics need to be bundled in a list. Change-Id: I2f196b37db0db95a5163696f14258a865fa9a615
