Find popular search terms using Edge Workers

This EdgeWorker serves responses for popular search terms at the Edge. Autocomplete requests are typically long tail and frequently changing. Without an EdgeWorker it is difficult to get up to date content from cache. Storing and serving the most popular search terms from the Edge will speed up responses significantly.
