Trigger Runner Command

This handler (com.rierino.handler.CommandEventHandler) triggers Commands on through Event streams.

Unlike commands, events are not broadcasted to all runners. Hence, triggering a command using this handler only causes a single runner to execute given command.

This handler is only used for simplifying development and testing processes, when a single partition runner is used and commands are not being sent through Kafka topics.
