Kafka producer action's topic config now supports templates.

The topics must be already created in Kafka. If a message is rendered towards a non-existing topic in Kafka (given Kafka disabled topic auto-creation), the message will fail with an unrecoverable error. Also, if a message does not contain enough information to render to the configured template (e.g.: the template is t-${t} and the message context does not define t), this message will also fail with an unrecoverable error.

This same feature is also available for Azure Event Hubs and Confluent Platform producer integrations.
