-- `/unthrottle-app/<app-name>`: remove any imposed throttling constraint from given app. Example:
+- `/throttle-app` can take a query parameter `store_name` to throttle the app only on one store (i.e. MySQL cluster). For example `/throttle-app/archive?store_name=mycluster` refuses `/check/archive/mysql/mycluster` requests for `1` hour.
