/**
 * Queries https://cdn.ampproject.org/rtv/metadata for the latest AMP runtime version. Uses a stale-while-revalidate
 * caching strategy to avoid refreshing the version.
 *
 * More details: https://cdn.ampproject.org/rtv/metadata returns the following metadata:
 *
 * <pre>
 * {
 *    "ampRuntimeVersion": "CURRENT_PROD",
 *    "ampCssUrl": "https://cdn.ampproject.org/rtv/CURRENT_PROD/v0.css",
 *    "canaryPercentage": "0.1",
 *    "diversions": [
 *      "CURRENT_OPTIN",
 *      "CURRENT_1%",
 *      "CURRENT_CONTROL"
 *    ]
 *  }
 *  </pre>
 *
 *  where:
 *
 *  <ul>
 *    <li> CURRENT_OPTIN: is when you go to https://cdn.ampproject.org/experiments.html and toggle "dev-channel". It's
 *    the earliest possible time to get new code.</li>
 *    <li> CURRENT_1%: 1% is the same code as opt-in that we're now comfortable releasing to 1% of the population.</li>
 *    <li> CURRENT_CONTROL is the same thing as production, but with a different URL. This is to compare experiments
 *    against, since prod's immutable caching would affect metrics.</li>
 *  </ul>
