/**
 * Listen for HTTP requests.
 *
 * This phase creates an HTTP server and listens for requests on the given
 * address and port, defaulting to 0.0.0.0:3000.
 *
 * This phase is typically one of the final phases in the boot sequence.
 * Initializers should be run and routes should be drawn prior to this phase,
 * ensuring that the application is fully prepared to handle requests.
 *
 * Examples:
 *
 *   app.phase(locomotive.boot.httpServer(8080));
 *
 *   app.phase(locomotive.boot.httpServer(8080, '127.0.0.1'));
 *
 *   app.phase(locomotive.boot.httpServer({ address: '127.0.0.1', port: 8080 }));
 *
 * @param {Number} port
 * @param {String} address
 * @param {Object} options
 * @return {Function}
 * @api public
