Listener Configuration

A Listener Object has the following schema. As long as the id is unique, a listener can be present multiple times.

// Listener Object
{
  // Unique identifier for this listener.  Used when looking up
  // configuration and reporting metrics.
  id: "console_logger",

  // The actor class used to build the Listener actor.  This allows for separate
  // concerns of managing the listener and implementing the listener.
  // See options below.
  builder: ConsoleLogBuilder
}
