// Updates a cache policy configuration. When you update a cache policy
// configuration, all the fields are updated with the values provided in the
// request. You cannot update some fields independent of others. To update a cache
// policy configuration:
//   - Use GetCachePolicyConfig to get the current configuration.
//   - Locally modify the fields in the cache policy configuration that you want
//     to update.
//   - Call UpdateCachePolicy by providing the entire cache policy configuration,
//     including the fields that you modified and those that you didn't.
