 * Complex scripted dashboard
 * This script generates a dashboard object that Grafana can load. It also takes a number of user
 * supplied URL parameters (in the ARGS variable)
 *
 * Return a dashboard object, or a function
 *
 * For async scripts, return a function, this function must take a single callback function as argument,
 * call this callback function with the dashboard object (look at scripted_async.js for an example)
