The DMaaP Mediator Producer provides Information Coordinator jobs that pushes messages from DMaaP Message Router to data consumers.
The producer is configured with environment variables. The ones defining the host of the supervision and job info callbacks are required to set before starting the producer. All other variables have default values.
DMaaP Message Router (MR) forces the user to poll a specific topic. Examples of topics are faults and metrics. So the decision has been made for a mediator job to provide messages for a specific topic. The first job to be provided will push messages from the fault topic.

The producer builds up a slice of all supported types during the type registration. This info and the callback URLs provided as environment variables during startup are then used to register the producer in the Information Coordinator. Should, for any reason, the registration fail, the producer will exit and log the cause of the failure. It will also exit if the callback URLs are not provided in enverinment variables at startup.
Server handler for status supervision only replies to "GET" method at the "empty" path. All other calls will return "404 NotFound".
